Have just color sanded the camaro this week, used mirka abranet 1k then abralon 2k with my DA. It really smoothed out the paint and what orange peel that was present.

Started buffing/polishing this weekend. Using 3m Perfect it radiused white foam pad and 3m 6060 extra cut compound. The paint really shines up well even before I have polished, but I am seeing alot of ultra small DA sanding circles in the clear (have not seen but 2-3 pigtails). So I buff it again a 2nd time in hopes that will remove the scratches but marginal improvement if any.

Any suggestions on a compounding system that will cut out the scratches better, and not really eat up my clear coat to much? Do I need to go over it again and wetsand it by hand , etc... any tips from here on will really help.

Those DA scratches are from the coagulated clearcoat that is removed when using a 'dry cut" (DA) system for polishing. What you are not told is that you need to "pound the pad" as I call it, - often - which is to tap the sanding disc to remove any particles and powder that clog the sanding disc - especially when using the finer grits like #2000 grit.

You can wetsand those areas with #2000 grit wet and then come back over it with a cutting pad and rubbing compound.

I find that foam pads used to cut/polish out the initial DA sanding is too time consuming for me and does not have the aggressiveness to cut out those minor DA markings. I prefer to use a double sided wool cutting pad initially then follow up with the foam pad and the appropriate polishes. Fropm my experience the DA scratches can be easily removed with the wool pad and rubbing compound.

hope this helps!

You can buy the Presta products and pads on ebay. Wool pads really do seem to make the difference as stated above.

thanx for the info guys... top notch. I have been using the 3m perfect it system, but after reading here about the presta line and googling more info their stuff, I may just spring for their kit with compounds/polish, and quick change pads.

Thanx again.
