I recently just bought myself a Balabushka GB-4 and some dings and scratches have started to develop. I was just wondering if it was possible to polish out some scratches that are developing on the stainless steel joint. I'm mainly concerned if this will alter the diameter of the joint and make it not be flush with the rest of the cue anymore. How much would this run me if I were to send it off to a cue repair person? Separately, how much would it typically cost to get my cue refinished?
