Looking for a 'professional' paint job on my rims. I have a set of 4 aluminum rims. They are 15x8's and are genuine 2 piece rims held together with rivets. Right now they are polished aluminum. I want a flatte black finish that will hold up well and last a long time. I'd do it myself but have no clue what kind of paint to use and don't have a lot of painting experience.
