I'm starting to think about painting my rig myself, although I have no qualifications whatsoever. I have some light rust on my 60 I want to take care of, and I thought I'd start testing the waters with a slightly rusty roof rack I picked up from another mudder. I did two coats of POR 15 (they really mean it when they say not to get it on your hands. Mine were high gloss black for 3 days!) Then scuffed it up with fine sand paper and did another 3 coats with rustoleum. It's considerably heavier than before. doesn't look too bad-- I didn't even lose any hardware when I took it apart.
