I the clear coat is gone, it is not because I did it on purpose. The car only has about 2,500 miles on it. I have polished the rims with some car wax and wheel cleaner, but not with anything that indicated it would remove clear coat or wasn't safe for modern wheels. I plan to take it over to the dealer to get their take on it. Several years ago when I had my '99 hardtop, I noticed a strange noise when I would turn the wheel all the way and slowly release the clutch. It turns out that the front wheels were cupped. GM and the dealer replaced all four wheels, which really surprised me. I didn't buy the car from that dealer so that really surprised me when they came back with that. Unfortunately, they lost all of those points when I picked the car up after they put the new tires on and notice a bunch of deep scratches in the rear lid of the car. Of course they said they didn't know where those could have come from, but agreed to buff them out. A couple were still slightly visible, but with a black car, it is hard to keep scratch free.
