On the Griot's polisher 5 still might be too high a speed setting. and like RZJZA80 stated above, you risk overheating the backing plate and thus the pads and this can lead to de-lamination of the adhesive between the Velcro and the backing material.

In this training video here, Jason Rose recommends using the 4 speed setting on the Meguiar's G110v2 dual action polisher. This is actually a very complete and detailed video showing exactly how to use this system on factory paint. He states the target OPM is 4800 OPM.


Fast forward to the 13:56 time mark.

Exactly.

Or the way I say it in my classes...

You need the combination of the oscillating action, the fiber, the abrasives, downward pressure to affect the paint before moving the polisher forward.


And by the word affect I mean abrade the paint, or in other words, for the abrasives to take little bites out of the paint in an effort to level the surface.

If you move the tool too fast you pad ends up simply skimming over the surface.


I'm working on the pictures of the 2008 Cadillac I used for my recent Detailing Boot Camp Class in which we used the Meguiar's Microfiber DA Correction System. The results were exactly what they should be and that's a like new finish.

The owner of the car told me his Cadillac looked better after my class was done with it than the day he bought it new from the dealership.


Technique is everything...

Great idea...

compounding paint correctly take time and patience. Its a slow process, especially for the weekend detailer.

If your compounding and by the time you are finished with one panel you look at the rest of the car and think to yourself " this is a ton of work !! and is going to take forever !" then your probably working at the correct speed. lol

You cant just go in jackhammer style and expect fast results.

Like mentioned above there is a bit of an art to detailing and the tools are not idiot proof. Everything needs to be taken into account. for example, machine temp, panel temp, backing plate and pad temp. how loaded your pads are, how much product you are using. too much ? too little ? how big your section is, how fast you are moving, the amount of pressure. this stuff cant be overlooked. and its easy to overwork your tools and make them degrade very fast as you have found out...

That's great....and SO true

Just by coincidence, check out this conversation in this thread in post #25

That's about right. For anyone reading this thread, if you're new to machine polishing, to take your time and do a good job for the first step, that is the most important step, for an average size car it's going to take you about 4 hours.

And that's just the compounding step. That doesn't include washing, drying, claying, taping off, etc.


The first step, the major correction step as I call it in my how-to book is the most important step and the step that will require the most time to do the job right.

You are not the first. Everyone things Griots is the machine to get for its power, but I wouldn't touch it. The machine obviously created too much heat for what it was designed to do. Many have fried/burnt/melted pads with this machine. The extra power is not necessary if the right technique is used.


I think the PC (old and new) is a better all around machine with all the power that is required. The other thing is, you mentioned the defects were minor. Microfiber pads were designed for fast cutting. They are generally more aggressive than foam. I would only be using MF pads for heavy defects that foam couldn't remove or the pad was overheating. Most regular swirls or scratches will come out with the correct foam pad and product.

You might have over loaded the pad or 'flooded' it with product. After the pad is primed I use two small drops on either side of the pad and work the section. That combination is a swirl killer so there is some sort of flaw in your technique (not to bash, but to provide helpful feedback).

If you can, you should post a video of what you're doing and maybe try down sizing the working area.

Good luck!

Use too much product and you hyper-lubricate the surface.

Use too little product and you won't have enough abrasives to do the work or lubrication to allow for good pad rotation/oscillation.

I want to add that like stated before proper priming and cleaning is key.. I have found that cleaning those discs with a brush just does not cut it. To clean them compressed air is that way to go. You are able to fluff the fibers back up and blow out all the spent product.

Another thing is after cleaning the pad its best to use small pea size drops I think it was said that after cleaning the pad and adding more product that less product is actually more with this system.

Keeping the DA at the 4800 opm's is big key. Too much heat and you will have pad failure. Too much pressure with the pad will cause the pads to become warped and then start to take a oval shape and begin to curl inward.

I also had issues with Megs Microfiber system the first time I used it. But once i got the hang of it it was awesome. Clean the pads often and slow arm movement. Just give it another try Im glad I did
