I don't know about clear floor epoxy. Maybe it would work. I use Nikolas spray cans that I obtain from Allied Supply or Ferrees. It is an air dry lacquer, and I really have had no trouble with it. You do need to be careful about temperature and humidity, or it will mess up the finish. Technique is very important. You have to start the spray away from the part to be lacquered, and move the spray continuously across the work piece and past the end. You have to get a coat that is wet enough to look glossy, but doesn't run. It takes a real feel and a lot of practice. Like someone else said, with airdry you can strip it and try again. Man, i don't know if I'd try a floor epoxy. But then I don't have any experience with floor epoxy, either.
