Hello All,

I have really ramped up my use of the DA. Question is say on the compounding stage (MEGS 105), how much product to you apply for each section pass? Do you apply an "X" on the pad after each 2x2 ft section pass area?

Next question is all in the same stage, stick with the compounding example, do you always buff off the product immediately, or do you so may the whole hood and buff off, or the side of the car and buff off?

Thanks!

Initially I apply a circle of product to a dry pad and then after there is enough product in the pad, I usually only apply 3 or 4 dime sized dots of product to continue onto the next section. I also clean the pad with a microfiber towel after each section.

I wipe the product off immediately after working the product over each area.

thanks for the update, I have been getting good results but I feel that i have been using too much product. The dime sized is a good reccomendation.

I like to spritz the pad with the pad conditioner and then lay a few lines of wax down. I then spread it out with my finger and try to cover the whole pad. After that I just put 3 to 4 dimes spots and get to work. I also wipe after each section and clean the pad after each panel.

just for clarification sake, you put 3 to 4 dime size drops on after each section correct?

Just prime the pad like I showed you when you were over or were you not paying attention-lol. DO NOT use anything else other than the product itself to prime the pad.

Man you should see the before and after on my in laws 2002 gmc truck, ohhh man its awesome. He was all like "all you need is the kit wax..." then I showed him what could be done and he was amazed.

But yeah we didnt do much more than my hood so I wasn't sure, the adhd must of been kicking in. I defintely remembered not to use anything else but the product.

So you don't recommend even using XMT Pad Conditioner (http://www.autogeek.net/xmt--pad-conditioner.html).

Sweet glad you are getting the hang of it. Let me know if you need anymore help.

Here's the deal...

You want AMPLE amount of product when first starting out because you pad is dry and some of the product is going to seep into the pad leaving less on the surface to LUBRICATE and ABRADE the paint.

So a good rule of thumb that has worked for THOUSANDS of people over the decades is st start out with either a Circle Pattern or X Pattern of product on the face of your pad. I tend to prefer a Circle pattern as a habit because as you work around the car you'll find that your product will migrate to the center on it's own, so I don't help it by using an X pattern.

http://www.autogeekonline.net/gallery/data/796/CirclePattern.jpg

http://www.autogeekonline.net/gallery/data/796/Xpattern.jpg



Another great method is to borrow from Kevin Brown's Method and that is to take your finger and spread the product out over then entire face of the pad so that when you first turn the polisher on the entire face of the pad is working for you.

I find from years of experience that by the time you do 2-3 "X-Patterns" or 2-3 "Circle-Patterns" and then simply go to work ALWAYS spreading your product out over the area you're going to work IMMEDIATELY, (like I explain in the below video), then in essence by the 2nd to 3rd time you do this the entire face of your pad is wet with product and you accomplish the same thing, (more or less), just by making sure that with each fresh application of product you spread it out over the area you're going to work before slowing down and making your "Section Passes".

[ame=http://www.youtube.com/watch?v=Q70g83mnTn4]YouTube - Removing Swirls with a PC7424XP How to do a Section Pass - Porter Cable[/video]



Make sense?

In fact if you buff out 2 - 3 sections and turn your buffing pad over you'll see the entire working face is equally damp with used product...

It's when you spread the product out quickly over the area you're going to work that you spread out and leave behind on the surface of layer of un-used product that you then pick up as you begin to work the area that helps to ensure that the entire face of your buffing pad becomes wet with product.

Bad technique would to to place some product on the face of your pad, place the face of you pad against the paint and then turn the polisher on and start moving the polisher slowly making over lapping passes. The problem is you'll push a lot of that product up into your pad and you'll do most of the correcting at the beginning and less towards the end of the section you're buffing. So first, spread the product out quickly and then slow your arm speed down and start making overlapping passes.


After your pad is broken in with product, clean your pad after each section pass and when you apply fresh product you can cut down on the amount of product you actually apply to the face of your pad. Someone in this thread said 3-4 dime size drops, I usually place about a 2/3rds circle pattern to the outer face of my buffing pad and get back to work. Remember you want enough product on the surface so you have,

A) Abrasives working for you
B) A lubricating film keeping and maintaining a wet film between the paint and your pad.


Often times if you don't have enough product you'll end up buffing to a dry buff and when you lose lubrication what increases? Friction.





Next question is all in the same stage, stick with the compounding example, do you always buff off the product immediately, or do you so may the whole hood and buff off, or the side of the car and buff off?

Thanks!

There's no benefit to letting an abrasive product dry on the surface, in fact it's usually easiest to remove compounds and polishes when they are still wet, so you can find a system that works best for you but my personal choice is to wipe off any residue immediately after buffing a section. Then clean my pad, then move on.

This is a pretty detailed write-up on how to use a DA Polisher from start to finish...

Tips and Techniques for using the PC 7424XP Dual Action Polisher to remove Below Surface Defects (http://www.autogeekonline.net/forum/expert-tips/20021-tips-techniques-using-porter-cable-7424xp.html)


Here's just a portion...


First, here's a few time saving tips that everyone learns when they're new to machine polishing.

1. Never turn the polisher on until the face of the buffing pad is in contact with the surface of the paint.

2. Never lift the buffing pad off the surface until you have turned the polisher off.

Like this,
http://www.autogeekonline.net/mikephillips/images/polish-2.gif

If you do either of the above, especially if you lift the buffing pad off the surface before the pad slows down after you’ve been buffing for a while and your pad is now wet with product, you’ll throw product splatter all over the car as well as yourself and anyone and anything nearby.

Next you'll put the polisher down and spend the next hour or so doing your best to wipe off a zillion little dots of product splatter off adjacent panels and everything else surrounding the buffer.

Most people make this mistake once, then after experiencing what a pain it is to remove all the small dots of splatter not to mention all the time it requires, then most people will never make this mistake again. So try to make it a habit to turn the polisher off and allow the buffing pad to slow down before lifting the polisher off the surface.

Now that we've covered this common mistake that everyone makes at some time or another when learning to use a DA Polisher, let's take a look at how to actually use the polisher to remove below surface paint defects first. After that we'll take a look at using the polisher to apply a wax or paint sealant and then to remove the dried wax or paint sealant.

Note; these techniques apply to your doing your Test Spot as well as all the sections you're going to break the panels of your car up into as you work around it.

Correction work – Using the PC7424XP to remove below surface defects

Work small sections at a time
Make overlapping passes as you work the panel
Use a slow arm speed
Use the 5.0 to 6.0 Speed setting when removing below surface defects
Apply firm downward pressure
Don't over use or under use your choice of compound or polish
Hold the pad flat to the surface
Clean your pad often
Remove spent residue before adding fresh product
Work small sections at a time
Dual action polishers that use a clutch, like this PC 7424XP (http://www.autogeek.net/porter-cable-7424xp.html) are popular because they're safe. The reason they’re safe is because if you push down too hard on the head of the polisher the clutch will engage and the buffing pad will stop rotating. This will prevent you from burning through the paint and/or instilling swirls into the paint. Compared to a direct drive tool like a Rotary Buffer (http://www.autogeek.net/circular-polishers.html), this tool is dramatically safer in its manner of operation.

For this same reason that people love this style of polisher, (It’s safe and easy to use), you'll find out right away that it also limits you to only working small sections at a time in order to remove enough paint to level out the surface and remove the defects. In most cases you're only going to tackle a section about 16" to 18" inches square or so; usually a 2' section is too large and a 1' foot section is too small, so you'll want to find a balance between working too small an area and working too large of an area at one time.

Since you can only work small sections at a time, this means you’ll need to break each panel up into small sections kind of like Checkerboard or Patchwork Quilt.


That is you’ll take each panel of the car, (a panel would be a door or fender or the hood), and in your mind’s eye slice it up into dedicated sections approximately 16" to 18” squarish or so. Because not all panels are perfect squares you’ll need to let the panel be your guide and break-up each panel into these smaller sections no matter what the shape may be. What’s important is to only work a small section at a time while using overlapping passes to work your product.

http://www.autogeekonline.net/gallery/data/723/detail-153.jpg

The average size hood will be broken up into either 4 sections for a small hood, (Mini Cooper), or 6 sections, (Honda Pilot), or 9 sections, (Ford F150).


This isn't a hard and fast rule as softer or more workable a paint means you can tackle a larger section at a time and conversely, with harder paints, or less workable paints you'll want to shrink the size of your work area down.

The idea being to match the size of the section you're working to the workability of the paint, which you should discover when you do your Test Spot, which is addressed in this article. Experience helps a lot with judging work size area but the only way to get experience is to put some hours behind the polisher on multiple cars.


Spread your product out first
To start, place the face of the buffing pad with the product on it, flat against the paint. Then turn the polisher on and quickly spread the product out over the entire section you're going to work. You can do this rather quickly because at this point you're not trying to remove defects; you’re just trying to spread the product out over the paint so that you have a uniform film of product spread out over the section.


Overlap your passes by 50%
After you spread the product out, now it's time to slow your Arm Speed down and begin making overlapping passes usually in a crosshatch or back and forth, side-to-side pattern.

The goal is UMR, that is Uniform Material Removal.

The reason for this is so that you remove an equal amount of paint over each section and in turn over the entire car. In order to do this you need a method that you can control and duplicate and for most people following a back and forth, side-to-side pattern works because it’s easy to remember, easy to do and easy to duplicate.


The definition of a pass
There are two definitions of the word pass as it relates to machine polishing with any type of machine.


Single Pass
A single pass is just that. It's when you move the polisher from one side of the section you're buffing to the other side of the section you're buffing. That's a single pass.


Section Pass
A section pass is when you move the polisher back and forth, or front to back with enough single overlapping passes to cover the entire section one time. That's a section pass.

Like this,
http://www.autogeekonline.net/mikephillips/images/polish-1.gif

In most cases if you're removing any substantial below surface defects you're going to make 6-8 section passes to the section you’re working before you either feel comfortable you've removed the defects or you're at the end of the buffing cycle for the product you're using.


Buffing Cycle
The buffing cycle is the amount of time you are able to work the product before the abrasives have broken down, (if you’re using a product that uses diminishing abrasives), and/or the product begins to dry and you lose the lubricating features of the product. Different products have different buffing cycles depending upon the type of abrasives used in the formula and the different ingredients used to suspend the abrasives and provide lubrication.

Factors that affect the buffing cycle include,

Ambient temperature
Surface temperature
Size of work area
Type of machine
Type of pad material
Humidity
Wind or air flow surrounding the car
Amount of product used
Technique
Wet buffing technique
Most compounds and polishes should be used so that there is enough product on the surface to maintain a wet film while the product is being worked. The wetness of the product is lubricating the paint as the abrasives abrade the paint and cushion or buffer the abrading action so the abrasives don’t simply scour the finish leaving behind swirls and scratches.


Dry Buffing Technique - Buffing to a dry buff
There are some products on the market where the manufacture recommends buffing the product until it dries. As the product dries you’ll tend to see some dusting as the product residue becomes a powder and the paint will have a hard, dry shine to it.

Although some manufactures recommend this, it’s important to understand what’s taking place at the surface level as you buff to a dry buff. As the product dries, in essence you are losing the lubricating features of the product and as this happens friction and heat will increase. As friction and heat increases, so does the risk of micro-marring the paint or instilling swirls either by the product residue or the pad material and/or a combination of both.

While we trust that the manufacture knows their products best, when we take a close look at what it means to buff on a delicate surface like an automotive clear coat, it doesn’t make sense to run a buffing pad on top of the paint without some kind of wet film to lubricate the paint at the same time. We always recommend that you follow the manufacture's recommendations and use your own judgment.

Everyone new to buffing wants to be told some easily identifiable sign that they can use to tell when it's time to stop buffing and it's not that simple, so here's an indicator I've always used and taught to others,

Wet film behind your path-of-travel
As you're making a single pass with the polisher, the paint behind the path of travel of the buffer should have a visible wet film on it. If the paint behind the pad is dry and shiny, you've run out of lubrication and you're dry buffing. Turn the polisher off. Wipe the residue off and inspect using a Swirl Finder Light to make sure you didn't dull or mar the paint, you usually won't cause any harm, but pay attention when your running the polisher and don't buff to a dry buff. If you do, you can quickly re-polish that section by cleaning your pad and adding a little fresh product and making a few new section passes.


Use a slow arm speed
The speed at which you move the polisher over the paint is called your arm speed, that is how fast or slow you move your arm which is controlling the polisher. When removing below surface defects like swirls and scratches you need to move the polisher slowly over the surface, not quickly. This has to do with the hardness or workability of the paint and when it comes to modern clear coats, generally speaking,

Modern clear coats will tend to be harder than traditional single stage paints.

This isn’t 100% true all the time as I’ve worked on some very soft clear coat paints, but more often than not this is the norm. Another way of saying this would be,

The paint on a brand new Mustang will be harder than the original paint that came on a 1965 Mustang.



http://www.autogeekonline.net/gallery/data/719/medium/RedMustangs.JPG


This has to do with how modern paints are chemically made, sprayed, baked, and cured onto the car’s panels. Modern paints tend to last a long time as compared to paints from the 1950’s, 1960’s and 1970's and part of the reason they are more durable is because they are physically harder than old style solvent-evaporation paints, thus they resist deterioration better than old style paints. And while everyone wants a paint job that will last a long time, it is this hardness factor that makes it more difficult for you and me to remove defects like swirls and scratches out of the paint because it’s physically harder to remove small particles of paint off the surface both by hand or machine. This is one of the main reasons so many people get so frustrated trying to remove swirls out of the clearcoat paint on their new cars, trucks and s.u.v.s.

It’s for this reason you need to move the polisher slowly over the surface, you need to give the buffing pad, the oscillating/rotating action of the polisher and the abrasives in the product under downward pressure time to affect the paint in one area before moving it forward to new territory. If you move the buffer too quickly over the paint you won’t remove any defects because you won’t remove any paint.

A personal note, maybe you can relate...
Even though I've been machine buffing cars since the early 1980's, and teaching people how to use machines since 1988, and a part of this is teaching people to move the polisher slowly when removing defects, each time I start a new project I'll find myself instinctively starting out by moving the polisher too fast.

My theory on why I do this and why so many other people do this is for two reasons.

1. When you turn the polisher on at the 5.0 and 6.0 speed setting, it sounds like the motor is spinning really fast, (it is), and this sound has a psychological effect that makes us want to move the polisher fast. I find I have to purposefully slow down how fast I'm moving the polisher over the surface.

2. Buffing out a car from start to finish takes a long time and the biggest chunk of time is the cleaning and polishing step where the defects are being removed. It's easy to think that if you move the polisher faster then you can do the job faster, but this just isn't true. Fact is if you move the polisher fast over the surface you're really not doing anything but wasting time. It's another case of moving slower in order to go faster. (That's what you want to do)


Speed settings for removing below surface defects
The variable speed dial on the PC 7424XP offers 6 speed settings from 1 to 6. For most car detailing projects you’ll use these speeds.

5.0 to 6.0 to remove defects
3.0 to 4.0 to apply and spread a layer of wax or a paint sealant
5.0 to 6.0 to remove dried wax or paint sealant using a microfiber bonnet
5.0 to 6.0 to remove defects
Removing below surface defects means removing a little paint. In order to remove a little paint you need the pad rotating against the paint under pressure with an abrasive product. In order to do this you need to use the 5.0 to 6.0 speed setting. This applies to any steps where you’re removing paint. This would include a heavy compounding step, a final polishing step, or working a cleaner/wax over a neglected finish.


For removing below surface defects use the 5.0 to 6.0 Speed Setting


http://www.autogeekonline.net/gallery/data/723/detail-179.jpg


3.0 to 4.0 to apply and spread a layer of wax or a paint sealant
After the defects have been removed and you’ve worked the paint up to a clear, high gloss you no longer need or want a fast rotating speed as you’re no longer trying to remove paint, so the 5.0 and 6.0 speed settings are too fast.

The exception to this rule is if you’re using a cleaner/wax on a neglected finish as a one-step approach. In these situations you need the high speed to keep the pad rotating to work the cleaners in the cleaner/wax to clean the paint and remove light defects.

When it comes to applying a finishing wax or paint sealant the goal is to spread the product out and work the product over and into the paint to whatever level is possible. For this the 3.0 to 4.0 speed setting works best. Anything slower than 3.0 is just too slow and your buffing pad will tend to feel like it’s dragging across the paint as you move the polisher forward. When applying a finishing wax or paint sealant, a good rule of thumb is to make 2-3 single passes over each square inch.

http://www.autogeekonline.net/gallery/data/723/detail-126.jpg


5.0 to 6.0 to remove dried wax or paint sealant using a microfiber bonnet
Some people like to remove dried wax or paint sealant using a microfiber bonnet over a buffing pad. When using the dual action polisher like this you need the pad to rotate and thus you need the higher 5.0 to 6.0 speeds. Just be careful to never lift your polisher off the surface with the motor turned on as the buffing pad will spin up to maximum speed and your buffing pad and bonnet will fly across the room and land on the floor. (Usually the dirtiest part of the floor and with the bonnet face down)



Apply firm downward pressure
For removing below surface defects you need to apply firm downward pressure to the head of the polisher. As we discussed earlier, removing below surface defects means removing some paint off the surface and this requires applying some pressure to the head of the polisher to engage the abrasive particles with the paint so they can take little bites out of it.

This is where hand-on training comes in real handy by someone with years of experience but I'll try to explain it with this keyboard.

15 to 20 pounds of pressure
If you place the face of the polisher on a normal household bathroom scale, it will read around 4-5 pounds, so just the weight of the polisher itself is supplying some downward pressure.

Now follow me, if you apply just LIGHT pressure to the head of the polisher to keep the pad flat and stable while it’s operating, you’ll be around 7-8 pounds of downward pressure right from the get-go. If you apply even more pressure to really engage the pad and the abrasives against the paint you can easily reach 15 to 20 pounds of downward pressure.

I know when some people read this it sounds excessive but it’s really not when you consider the pressure by just the weight of the machine already is around 7 pounds of pressure, and with just light pressure you’re already at 10 pounds of pressure.

Take my word for it, when trying to remove a little paint from some cars it’s going to take some downward pressure to engage the abrasives into the paint and do any serious correction work. The key is to remember that polishing paint is an art form and anytime you have to use an aggressive approach to remove a little paint chances are good you’re going to have to do a follow-up step to refine the finish even further using a less aggressive pad and product. So the results from an aggressive product with downward pressures of 15 to 20 pounds won’t always leave a pristine finish but that’s okay, you’re not finished yet. (No pun intended)

As a general rule of thumb, when working on seriously neglected paint, you'll want to apply firm pressure but never so much that the pad stops rotating. This is the purpose of the black lines on the back of your backing plate and/or foam buffing pads, it’s so you can easily see if your pad is rotating or simply vibrating against the paint. Paint is removed best when the pad is rotating, not simply vibrating.

Keep in mind you need to balance how much pressure you apply to the condition of the paint and what you’re trying to accomplish. If the paint is in good condition and only in need of light correction, (shallow defects), then you won’t need to apply as much pressure. If the paint you're working on looks like it's seen a Destruction Derby, then increase your pressure to anywhere from 15 to 20 pounds of pressure.


Hold the pad flat to the surface
It's vital that you hold the buffer in such a way as to keep the pad flat against the surface while you're buffing. With a completely flat panel like the hood of most large cars and trucks, for example a 80's era Suburban, it's pretty easy to keep the pad rotating by holding the buffer evenly as you buff.

With panels that slope or curve, you need to rotate or adjust how you hold the body of the polisher to match the curve of the panel as you move it over the paint.


If you hold the polisher in a way that there is more pressure on only an edge of the buffing pad, this increased pressure to one section of the face of the buffing pad is enough to stop the pad from rotating. This will be easy to see from the marks on your backing plate and paying attention to how you’re holding the polisher in relationship to the shape of the panel. Watching your pad will help you to perfect your technique.

It's not as difficult as it sounds and most people new to using a DA Polisher will learn how to hold the polisher while adjusting for the curves and slopes of the car after buffing out just the front clip of their car, (hood and front fenders). The learning curve for a DA Polisher is pretty flat, that means it's pretty easy to learn how to use.

Use an ample amount of product
When we say use an ample amount of product this means don’t use too much product and don’t use to little product.


Too much product

If you use too much you can hyper-lubricate the surface and this will make it more difficult for the abrasives to abrade the surface as they’ll tend to want to glide or slip over the surface instead of bite into the surface.


To little product
If you use too little product there won’t be enough lubrication to enable the buffing pad to rotate and thus engage the abrasives against the surface so they can bite into and remove small particles of paint.

Learning how much product to use varies with manufactures products as there’s a lot of variables involved. The best teacher is experience coupled with any hands-on training you can find. Watching a video or asking questions on a detailing discussion forum like the Autogeek Online Detailing Forum (http://www.autogeekonline.com/) is a great resource for this kind of information.

Also, when you’re first starting out with a dry pad, (doesn’t matter so much if it’s new or used as long as it’s clean), the pad will tend to absorb some of the initial product applied to it or picked up off the surface. As you continue to buff and the pad becomes more wet or saturated with product a couple of things will take place:

You’ll find you’ll need less product to work a section. As the pad becomes wet with product, the combination of liquid and foam will tend to absorb and dissipate the power provided by the motor. This will show up as a reduction in the ability of the tool to keep the pad rotating under pressure. Then if you apply more pressure the clutch will engage and the pad will stop rotating. The fix for this is to clean your pad often, which we will address below and/or switch to a fresh, clean, dry pad and continue switching to clean dry pads as you work around the car and your products become wet with product.

Of course the ability to swap out pads means having a collection of pads in your arsenal to start with depending upon your budget and how much you value your time. Simply put, dry pads rotate against the paint better than wet pads, so it’s faster to buff out an entire car by swapping out wet pads for dry pads versus trying to buff the entire car out with only a few pads.

New generation DA Polishers like the PC 7424XP and the Meguiar’s G110 (http://www.autogeek.net/meguiars-dual-action-polisher-g110.html) offer more power than their predecessors and this is their strong point because it’s this extra power that will keep your pads rotating better even after they become wet with product. This one feature alone makes them worth choosing over earlier dual action polishers and/or upgrading.



Clean your pad often
Anytime you’re buffing with an abrasive product, whether an aggressive compound or a light polish, you have two things building up on the face of your buffing pad,

Spent or used-up product
Removed paint
You need to remove these residues often by cleaning your pad either with a,

Pad washer
Pad cleaning brush
Terry cloth towel using a technique called cleaning your pad on the fly.
Again, we cannot stress enough the importance of working clean and in this case it means wiping any spent product off the paint after each section pass and removing any spent product and paint residue off the face of your buffing pad with one of the three methods listed above.

If you don’t clean your pad often then usually you’ll find that your product will become gummy on the surface of the paint and wipe-off will become more difficult. Not only that, but as product residue builds-up on your paint you increase the risk of instilling swirls back into the paint.

Adding fresh product to used-up product dilutes and pollutes the fresh product, making it less effective. So make it a best practice to clean your pad often and always wipe off spent product before adding fresh product.


How often to clean your pads?

Car body panels
At a minimum, wipe all spent product and paint residue off the car after you finish each section and always wipe the paint clean before re-polishing that section a second or third time with fresh product.

Buffing pads
This is personal preference and here’s what I do, for the average condition paint I will tend to clean my pad on the fly every other application of product. This means if I were buffing out the hood of a car I would apply my product to the face of the pad and buff out a section of paint about 20” square or so. If I’m done with that section I would wipe the residue off and then buff out the next section and be sure to overlap a little into the previous section. Now, after I’ve buffed these two sections I would clean my pad on the fly and then start on a new section and repeat this method as I work around the car.

If the paint is severely neglected and I have to really get aggressive with the paint then I would clean my pad after each application. Also, if the temperatures are hot then I would clean my pad after each application as this will make buffing easier and more effective with less problems associated to the product trying to dry and/or become gummy on the surface.

If you have a pad washer then you can follow this same routine. The most effective way to clean a pad while working on a car is by placing the pad on a rotary buffer, (even if you’re not using a rotary buffer to do the buffing work), and use the direct drive rotating action the rotary buffer offers to spin the pad in the pad washer at high speed and under pulsating pressure to really get the pad clean. Then lift the pad up a few inches and bring the rpm’s up to the buffer’s highest speed and spin out all the water via inertia. Now your pad will be clean and ready to get back to work.
