Painting wheels

I just used duplicolor engine enamel on mine. Then again they're just stock rallyes and I didn't care too much how it turned out. One wheel came out really nice, but the others had some adhesion issues, think there was still some tire black or something on the rims. First one was nice, second one noticed the running, scrubbed the last two pretty good but same problem. i like the powdercoat idea though. The engine paint works nice and seems fairly resistant, but it's a little on the weak side, tightening the lugnuts will flake it off some if you aren't careful.
