Catalyzed lacquer vs. polyurethane...

My wife collects orchids and we are getting ready to build some more birch cabinets to display them. I need a clear coat for the interior that can withstand humidity and some direct contact with water droplets.

In the past we have used Minwax oil-based polyurethane or Envirotex-Lite, a solvent free epoxy. We're looking for something different.

Oil-based poly is just a bit less water resistant than we'd like. It's also a lot of time to put on enough coats and have them offgas to the point that it is safe for the orchids. What we really don't like about it is having to repair or recoat it after a few years. In fact OB polyurethane's water resistance would be fine if it were easier and quicker to repair or recoat.

The Epoxy is nice but a bit fussy and very expensive.

So we're looking for something that...

1) is equally or more water resistant than oil-based polyurethane.

2) is a sprayable finish.

3) can be built up and act as its own sealer.

4) allows easy repairs with minimal turn around time.

We don't mind a slightly plastic look or paying close to epoxy prices.

So I'm wondering how a catalyzed lacquers/conversion varnishes stand up to our criteria?

I appreciate any input.

how about simply using johnson's paste wax?
apply a new coat when ever you feel it needs it.
simple, easy and water repellent.
tape off the glass and go for it.
