Re: Mark Your Backing Plate - Makes it easy to see Pad Rotation
Lots of good information in that video Mike. I hope to see several more videos such as this.

Re: Mark Your Backing Plate - Makes it easy to see Pad Rotation
Such a simple tip that I picked up previously from you, Mike....excellent reminder post.
Having that line makes a huge difference in knowing if you're applying the right amount of pressure. I've foudn I also now know how fast I want the line moving around based on what product/pad I'm using....

Re: Mark Your Backing Plate - Makes it easy to see Pad Rotation
So if the pad is just vibrating and not (SPINNING) it means ur putting down too much pressure to the polisher right?

Re: Mark Your Backing Plate - Makes it easy to see Pad Rotation
I didn't watch the whole 42 min of the video, but from just watching about 5 min of it, I noticed you just used a more aggressive product on certain areas/spots.
So if I just have a couple places that need a more aggressive product/pad, can I just use the more aggressive product/pad on that area/spot and not have to go over the entire vehicle with the more aggressive product/pad?? I didn't know if that would affect the clearcoat.
For example, if I need to use Megs 105 and a orange pad on one spot, I don't have to go over the entire car with Megs 105 and orange pad? And then use a less aggressive product/pad like Megs 205 and a white pad on the rest of the vehicle?
If you always do, what you've always done, then you will always get what you always got

As your question applies to a DA Polisher like the PC, Megs and Griot's, if the pad is just vibrating or jiggling, but not rotating it could be,
- Too little pressure - There's a quirky thing about these tools that if you hold the pad just right against the paint as though barely touching it the pad won't rotate like it does under pressure but more or less just flutter and even rotate backwards or counter-clockwise.
- Too much pressure - If you apply too much pressure you can stop the pad from spinning, this is the safety characteristic that Newbies love and experience people forget about after they master the tool and then complain because the pad stops spinning.
- Uneven pressure against pad - If you don't hold the pad flat to the surface, that is you hold the body of the tool in a way that pressure is greater to just an edge or side of the face of the pad you can easily stop the pad from spinning. This is more noticeable with larger pads like 6.5" and 7" pads as the larger the diameter the pad the more leverage the pad has over the spindler/drive mechanism.
- Raised body line - If you're buffing on a raised body line there will be more pressure to smaller area of the face of the pad and this can be enough to stop or slow down the rotation of the pad.
- Convex or Concave shaped body panel - Like a raised body line, if you're working on a convex or concave shaped body panel you can have more pressure to the outer edges of the pad or the inner portion of the pad and this can stop the pad from rotating or slow pad rotation down.
- Too large a pad - When buffing with larger pads the larger diameter of the pad give the pad leverage over the spindle and this can stop pad rotating or slow pad rotation down.
- Wet or saturated pad - When a pad becomes wet or saturated with product the combination of foam and liquid act to absorb and dissipate the energy coming out of the tool and this can stop or slow down the rotation of a pad.
See this article for more information on how the drive mechanism for these tools works....

Watch the below TV show starting at the 10:30 mark and I will show you not only why the PC style tools are so safe but how too much pressure will stop the pad from rotating. (against my hand )

Yes, but keep in mind, after going over these areas with the more aggressive product you need to make a few cover passes using your less aggressive pad and product combination to make sure you don't leave any haze or micro-marring behind from the aggressive product and pad.

Correct.

Correct.
If you've already buffed out the car and you're just doing some "Spot Repair", then you only have to do the M105/M205, (or whatever your compound/polish products are), to the spots you're working on.
You can as an option re-polish the entire car and the re-apply wax because nothing looks as good as a freshly waxed car.
