But your in the right church just the wrong pew

Check you local paint stores for someone who sell Rustoleum Indutrial Epoxy. This product is made for painting Cement mixer trucks and dump trucks. One of their sales aids is they hand you a peice of sheet metal primed and painted with this product they then hand you a ball pien hammer and say pound on it from both sides. A lot of paints when the metal is impacted from the back side will pop off the surface. This product does not, it sticks. I even had the sale rep leave me some product and I made my own test panel just in case factory application made a difference, I worked like a charm. Now the most important thing with any paint job is surface prep. I suggest having the tires remove use a semi-paste paint and varnish remover and then wire brush scotch brite pad and or steel wool and try to clean them down to bare metal then use the reccomended primer and top coat allow plenty of drying time and proper temperature when applying. The longer you allow the paint to cure and harden the more bullet proof the finish will be. Save a little extra for touch up if needed after tires are mounted and balanced and I think you will be very pleased. I takes a lot of time effort sweat and patience, but you will have years of service and good looks for your wheels.

Good Luck and take your time.
