Painting wheels
I will consider powder coating them once I decide what I want them to look like, not sure if they will end up black or gun metal center with polished lip.
As for the caliper paint, that's what the guy told me they were painted with and that crap is fairly difficult to get off...They are 17x8 bullitt wheels by the way, and for $100 for 4 of them I'm willing to "try" on them ;)
...Engine enamel, novel idea, I used that stuff on the engine and it holds up will against heat and degreaser, just have to see about getting the finish to look nice enough...I guess it didn't occur to me..
