Good points about the cadmium plating process...
Unfortunately, most off-the-shelf engine paint products wouldn't withstand the heating/cooling cycle of discs.
Ever watch those TV race-cams that they mount behind the one of the wheels of a race car? You can see the discs glow bright red every time the driver brakes, and immediately dissipate once the pedal is released and air is flowing again!
That's torture for any product not molecularly bonded to the disc!!!
