Just thought I'd share some photos as some of you have asked about this very simple process. If you've recently replaced your OEM rotors, chances are they were not zinc-protected, and thus you saw your shiny new silver metal quickly turn to a brown, rusted color. The solution: simply paint the rotor hubs!

Step one - get the car off the ground and remove the wheels:

Step two - Clean off the rotor hub surface with a wire brush. I use a compressed air grinding tool with two different types of brush heads to get all the nooks and crannies:

The paint I used was a high temperature engine paint:

Step four - Let the paint dry! :idea:

The finished product:
