I was chatting with someone about how my SUV seems to warp rotors all the time. He said, that, for years he would buy high heat paint, and paint inside the rotors.
I'm concerned thinking that part is for heat dispersion and wouldn't that actually warp them? He recons that the heat dispersion is affected when the inside rusts and swears that he has never had a warped disk and that it is a good thing to do.
Is this a good idea or a bad idea?
