New hubcaps could have been purchased for about fifty bucks each, but being a cheapskate at the time, I opted to slueth out hubcaps via the internet; ebay, facebook groups and the P15-D24 forum. I ended up with two pretty good candidates and fours that were on the sketchy side.
Removing the thick coat of rust from the backside took some elbow grease. I let ’em soak in vinegar for a few days then scrubbed them with steel wool and green meanines (Scotch Pads). The front sides I cleaned up with rubbing compound then applied a degreaser before I started the masking and painting.
With 1/4 inch masking tape, outline the main circle. With 1/2 inch tape, add some margin to the circle then use newspaper to protect the rest of the hubcap. Use 1/2 inch tape to cover the lettering. Finally, cut out the letters. You can see some of my color testing here.
After using a paint prep degreaser, such as the one made by Dupli-Color, use an off the shelf primer. Think Rustoleum.
First thought was to have a custom color blended by Finish Masters. However considering how rough these vintage hubcaps are it didn’t make sense, so off the shelf Dupli-Color rattle can that was “close enough” was selected and sprayed.
