Water-based "polyurethane" is not alcohol-proof, even when fully cured. In other words, it is not a suitable finish for furniture, floors, counters, bars, or basically anything. And that's any kind of alcohol, including drinking alcohol. As far as I am concerned, that is no kind of finish at all - as bad as lacquer. I'll go forward with this debacle because that seems to be the easiest thing, but now I have an alternative if need be - I know what I can strip it off with.
