scratches in paint

I painted the car with ppg shop line black bc/cc. I am buffing it with 3m perfect it foam pad using 3m extra cut compound. I use the 3m swirl remover and it shines up great but I still see the scratches from the 2000 grit sand paper. I mean plain as day see them. I wipe after each buff with a grease and wax remover. The sand paper I am using is the stuff from a local auto parts store maybe its not a true 2000 grit? Should I buy a wool pad? Maybe go with a higher grit sandpaper. Please help

What grit did you sand the primer with before you painted? After the paint has cured a few days it tends to shrink a bit and the scratches in the primer will become visible.

i sanded the primer with 400 grit before base coat. I can tell where I sanded with 2000 grit and that is what I am seeing.

I think the foam pad cuts slower than a wool pad, maybe just buff it again with the foam pad.

I am not impressed with the 3M Extra Cut compound, it is no where near as agressive as the old stuff. The guy I had buff out my paint job used some 3M compound that was a light tan color and came in a transparent bottle. It was the only thing that would cut the PPG DCU2002 and get rid of the wetsanding marks.

How many coats of clear and what type did you use? You may need to go to a more aggressive compound. The guy that did mine stayed with the foam pad with the more agressive compound. No need to switch to a wool pad IMO.

There's alot of ways to do this that will work. But basically, the compound, the pad, the speed, or the method is wrong. The first thing I would try is a wool pad with the same compound you have. Hopefully that will work. If the clear is too soft or the method too agressive, the lines left will not be the straight sanding lines you are seeing.
What I use is 3M Imperial Microfinishing compound with a wool pad to start. Then I use the same compound with the softest foam pad I can find. I won't glaze until it already looks glazed. This always works for me but others swear by other methods. I think it would take a long time to buff without the wool pad.
