This is the biggest of the Audiovoxes, weighing in at a full 12 pounds, with a 36" scale. The neck is a Brazilian Cherry (Jatoba) floorboard over maple, with a straight cutout headstock. There are over 100 marker dots. The body is veneered masonite over solid plywood, with Danelectro-style Tolex binding. There are also strap buttons, this instrument can be played vertically or horizontally.
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.
