Hi, serious newbie here. I just got started in powder coating because I wanted to do parts off of my motorcycle, I have been reading this forum for a couple of months now and your tips have helped me get started successfully. I’m very pleased with the results I have achieved so far. A couple of the small parts I have coated have been over anodized aluminum and turned out great, one of my next projects is doing my wheels which are also anodized. But I had a friend tell me that I should remove the anodized finish first. So my question is, Is it necessary, will not removing it cause problems later? I appreciate your help and experience.
