I have zero plus one wheel. (My bumper experiment was a disaster.) I used some instructions posted on here. I'll look for it later, but in summary I cleaned up with a red Scotch pad, no sanding. I degreased with lacquer thinner. Then 2 coats Duplicolor Etching Primer because I was down to bare metal in places, 3 coats Duplicolor Sandable Primer, sand lightly with 600 grit, 4 coats Graphite Duplicolor Wheel Paint, 3 coats Duplicolor Wheel Clear Coat (all from NAPA). I'm very pleased, but I have some boo-boo's from the mount/balance. I'm putting on new tires so I'm doing them unmounted, one at a time. You can also do the index card trick and do it with tires on.
EDIT: I see you found the thread I was talking about. Good luck...
