just don mine, easiest way is, take it off......its easy, and the gasket is rubber so you can re-use it. clean it with gunk or something simalar.... make usre its absolutely clean and dry, then spray it with caliper paint....as a primer.... then whatever colour you want after that. but remember to laquer it, cos the paint wont like oil.
good luck.
mines AJ4 Flame Red at the momet with silver leters and looks the mutts nutts, plus it has the Fusion-motorsports.com logo in white at the top left with a nismo oil cap...braided steel hoses and all other ancilliary hoses and cables hidden arround the engine bay.,
its looking quite neat and tidy actualy. but no one is gonna see any pics of my car untill i have finished the whole thing. ill have a before and an after...
