Restoring the hubcaps. I decided to freshen up the hubcaps a little. 3 were a faded gray, and 1 was a darker color, almost blackish gray. My first step was cleaning the area between the chrome and the paint. The tape line. I used 0000 steel wool. Then I degreased it and applied 1/4" fine line tape all the way around. It really helps to see so I used these magnifying goggles and a headlamp, and a good light. Once I had that tape on, I used a wider tape and continued around until it was masked off. Same for the center cap. Then I used a scotch Brite pad and scuffed and cleaned the old paint. Blew it off with air and degreased the old paint until the rag was clean. It took several cleanings, but this is a very important step. Then when the wind quit blowing, I gave them several coats of the Datsun Gray paint purchased from California Datsun, great stuff! An hour later, I removed the tape. It came off easy, pulling at a right angle to the paint.
