I have never had the oppertunity to refinish a Schuler cue. I have refinished hundreds of cues, but never one of these. The owner of this Schuler tells me that the aluminum sleeve, at the joint is held in place by a rubber "O" ring (not glued). Is this true & if so how do you recommend that I treat this sleeve, when sanding & spraying? Please don't offer an opinion, unless you KNOW the answer. THANK YOU IN ADVANCE...JER
