I'd really like to polish the outer rim on my turbine wheels while leaving the throwing star cover painted. I met a guy today who had done this himself using sand paper (starting with 900 grit and working his way up to 1500 grit). I'm sure how he finished them, I think he went to a shop. Has anyone else tried doing this themselves? His wheels looked awesome. Any information would be appreciated, even if it's just a shop name in the Boston area. Thanks!
