The trick is to make sure the calipers are clean,clean,clean. You can paint still on the rotor or take the calipers off the rotor. I left mine on the first time and masked the areas that I did not want to paint. I did mine the minute I got my pony home. First I cleaned with brake rotor cleaner and dried completely.Mask off the non-painted area. I always use VHT Brake Caliper&Drum paint. This is a high temp paint that has a real nice gloss to it. Easy to wash off the brake dust and looks great. One of my winter projects will be crossdrilled rotors and I will clean and paint better with the calipers off the car. You can get the VHT online or at many car parts stores. I use it on all my cars and it never peels and also cleans up great. Like I said in the beginning,make sure they are clean. Good luck and once done you will love the look..
