Coloring rotor hat questions

[carbuff]

The guy who did the ceramic coating on my exhaust system says that he regularly does rotors for exactly the reason you are concerned about (rust) and for appearance reasons. He said you just take them to a brake shop after and have them touch the surface with the lathe as if they were turning them to clean up the braking surface, and you're good to go.

That's an interesting idea, however I'd be concerned about the potential negative ramifications associated with putting a thermal barrier on the cooling surfaces of a rotor, particularly the cooling vanes, since that would somewhat defeat the purpose of the rotor to convert kinetic energy into heat and dissipate it. There are nearly limitless types and variations on ceramic coatings these days, but most serve as good insulators, hence their use on exhaust and other similar applications where excessive heat transfer is not desired.

Here is an article on ceramic coating with rotors from swaintech..

There is a few patents on it, but one references wear resistance.
