I have a billiards cue of EsBee. I gave it to a very good friend of mine who is our local cue maker/repairer. He refinished the half butt (handle and butt area) but he left the forearm due to the fact it is stained maple and it has the signature. He can't find the way to refinsh this part and keep the signature and not "hurting" the stain part. Any ideas?
