Review for 'Cue Doctor Dent Buffer'
While the actual product itself is well made how it works causes damage to the cue. This tool actually compresses the wood fibers around the dent making it larger but less noticeable. You're better off stripping any finish off with a Magic Eraser and using a drop of water to pop the dent back out. After a few hours use a Q-Wiz to polish the shaft back down and seal it.
I would not recommend this product to a friend.
