Default Coloring rotor hat questions

I have a set of rotors that don't have any protection from rust. I was thinking about painting or powder coating the area where the pads do not touch. What have other people used for this?
Thanks,
Jon

Black BBQ paint...high-temp, low cost, decent corrosion resistance with minimal thickness. I've also run exhaust paint from my 2-stroke ATV days with good results.

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.

Black Oxide. There are shops that can do it pretty much around the country.

I wouldnt use black Oxide.. Its meant for oil filled environments. Tends to rust pretty quick.

Wilwood uses E-coating on their rotors. Here is a few options from the finishing website. http://www.finishing.com/169/78.shtml

I am doing the same thing -- the shop that installed my brakes scratched up the hats and they need to be painted. I was thinking of using high temp caliper paint like a VHT High Temp.

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

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