I bought new to me reman. calipers for the rear s/n 95 I would now like to prime and paint them. Can anyone give me ideas for getting the oil off of the calipers from the reman. process. I am concerned about chemicals that might attack the rubber seals, could I use good old brake cleaner or does it leave a residue that paint will not stick too? Also if I buy auto zone type rotors should I prime and paint the non-pad surfaces?
