Thanks for the great input everyone! Nice to have different options. I'm encouraged by the number of waterborne products. Solvent-based lacquer is super easy to spray, it dries fast, but it doesn't do well in heat/ humidity. I don't have a shop right now, so I'd have to spray in the garage/ outside, and that means waiting at least another month or it'll blush more than a nun at a harvest festival.
Looks like I have a trip to Klingspor in the near future and check things out.
@drw Don I never heard of white poly before, the finished product looks great. I assume you have to sand between coats. Did you put any kind of primer or sealer on it first?
