no matter what i own i paint the wheels on it. if they are OE or not most of the time silver wheels are easier to find and i just make them black
make sure you scuff em up really well and you won't have a problem i just painted my OE wheels recently and they came out really well a member of this forum can vouch for that. took about a day to do it all, scuff, prime, paint, cure. nothing wrong with painting wheels i like it
