I use a friction polish and paste wax afterward. Probably not the best choice of finishes seeing as most of the bottle stoppers will be used with alcoholic beverage bottles :eusa_doh:
I would suggest spray lacquer.

Sorry, Gary, but I'm going to have to ask everyone to stop posting replies to your question until we see some proof of your work. Nothing is for free around here and we demand pictures (and a description of the wood type!!!)
