I just sent The X Man one of my sets of Juliet glasses, but I want to give the custom route a go on my own on another set. I have a set of plasma juliet glasses and I have access to a powder coating machine and oven as well as a sandblasting table. I am pretty sure that I will not want to sandblast the frames, but would using shells or beads be better as for getting the finish off the metal so I can powder coat them? Second, as far as the powder coating goes, should I put an old set of lenses in the frames while I coat them to keep the channels clean or will they be okay? thanks in advance.
