We had an aluminum frame/cromo fork bike media blasted and powder coated by a local shop earlier this year. We made sure that we had something in any of the braze on attachments so that they wouldn't potentially get clogged up during the powder coating process. Turned out absolutely beautiful. We had reproduction vintage decals re-applied with clear coate over them, can not tell that it isn't a brand new bike....of course it was getting all new components, so it IS a brand new 1989 bike, lol.
