That link to the old discussion tells of the paint I used. The reverse side had already been painted by the guy I bought the wheels from and it looked good. I used the PY (Performance Years) paint for the silver and had the charcoal custom mixed to the color codes mentioned in the FAQs on another part of the 1st Gen site. (https://firstgenfirebird.org/FAQ/wheel_brake_axle/rims.html)
I have not yet run the wheels on the car so I don't know how they will hold up to use, cleaning, and waxing. They look fine after 4 years of sitting in the basement and now the garage.
