You should strip the outer part of the rim chrome and keep a strip of black where the nipple are still intact. Maybe tape off the middle area and sand the outer edges. So it's like a black rim with a chrome lip. I dunno just an idea.
I found some stripper that would take off the powder coating so i'll just do the whole thing(I already have them taken apart). have some red nipples and blue spokes too so i hope it looks good.
