I'm planning on doing it. Scuff it all up w/ like 300 grit. DupliColor Adhesion Promoter, then some good ole matte black or gloss to match my steelies. I'll probably clear it. Mask off the ford emblem of course....gotta keep some bling.
I painted my chrome ones that came with my wheels, I wouldn't recommend clear coating them cuz I knicked mine up a few times and the peeling clear coat looks kinda haggard, but the paint never chipped. I used rust-o-luem professional from lowes
