OK, so I'm building a 4x2x2 cage for my little tortoise. Now it's going to have several inches of dirt and plants, etc in the bottom so a few coats of urethane isn't going to cut it. I need to be able to waterproof the entire interior (not only is the bottom going to be full of moist dirt, but it is going to be holding 80% humidity as well). Someone mentioned fibreglass epoxy, but I would like something a little easier to use that I can do myself. I *was* planning on using marine enamel until I heard that the stuff offgasses like CRAZY
Any thoughts on this? Does anyone have any other ideas? I'm at a loss for anything.............
