My son has a set of aluminum wheels that had the low profile wheel one them, he got a little to close to a curb and scraped them up pretty good. He asked if I could sand and buff them out. I fooled around a little last nite and noticed when I sanded with my die grinder it seemed to let a burnt mark at edge of working area where undamaged area started. What do I have to do to get the finishs to match up after grinding out scratches. I not really concerned with the low spot I might let after finishing I just want to get the ugly scratches out. Are these wheels clear coated with something, maybe that is why I see the burnt area around the perimeter of work area. Any help would be greatly appreciated.Thanks

I think you put your finger right on it. The darkened marks is probably the burnt edge of the clearcoat.------------------

I hit on a mind-bogglingly simple technique the other night to tell if an alloy rim has been given a clear coat of paint. If you use chrome polish on an uncoated rim, there will always be a little black residue on your cloth, even if the rim is really clean. If it's been painted, there won't be any residue, no matter how hard you rub.
I don't know if the same test applies to a powder-coated rim. Anyone?
