Just reading on tire sizing, see you had rims fresh painted. Do you know or recall the paint code or color. Mine are gone out for sand blasting right now, and then repaint.
When I repainted them, I worked for E.I. DuPont Automotive finishes. At that time I made up a silver BC/CC but don't remember the code or formula. It may have been waterborne basecoat, that was new then. Wow, that was over 31 years ago.
