I did a set of wheels for my Denali. I scrubbed them clean in the bathtub, then sanded down the entire surface with fine grit sandpaper. I then used prep-sol to remove any dust and oils left over. Once a paper towel with prep-sol would wipe clean on the surface I finally began to paint with Rustoleum spray paint in flat black. I did at least 3 coats then had the tires mounted 4 days later to allow time to dry. They held up great to driving in deep snow with TONS of road salt in upstate NY.
