I recently had the front rotors and pads on my '99 Cougar V6 replaced with new ones because the old rotors were mechanically fine but badly rusting on the outside, making the wheel look like crap. The tech applied some sort of high-gloss, high-temperature brake paint to the visible outside part of the rotors so that they wouldn't rust so readily, and it looks great except there's a small black paint spot on one of my wheels. :banghead: (I have the 15" factory alloys, by the way.) Is it safe for me to use paint thinner to remove this spot, or will that do more harm than good? What's my best course of action here? Any help would be appreciated.
