Shoulda showed you a "before" shot, but whatev. They look awful.
I blasted the rim, then clear sprayed it. I have sand in my little spot blaster, then visited a pal with his box blaster. We decided his was another silica media cause I didn't want to use an oxide that could rust spot the alloy rims.
The center cap got wet sanded to smooth the edges of the peeled plating, then I used some chrome paint on them.... turned out nice although I don't know how well that stays on.
