Yesterday the glass Rx Cue Dr, that I ordered came. I found that you can work out small finish dings on the handle somewhat if they're not too big. Last night while I was waiting for my girl to finish having a smoke, I was working on a small ding on my breaker. A non pool player came over and asked what I was doing. I showed him the glass rod and told him it was made of very delicate special glass and that by rubbing the rod on my cue, that I was training the wood molecules to all run in the same direction so that my cue would break better. He just looked at me and said, "really, wow". and walked away.
