Hello - I just bought new barstools that swivel and somtimes when they do (swivel) the wood part bumps my granite counter. I would like to protect the wood from getting banged up by applying a good finish over the one I have. I don't know what the existing finish is on my barstools. What will happen if I apply, say polyurathane over lacquer? Any suggestions on what to do? Thanks in advance!
