Hey Linds .. you can also get water based elastomeric coatings that are used for roofing. I painted the inside of my tall rainforest cage I'm building with it and have tested it with about 1 foot of standing water for a week without any problems. I put on a coat of Minwax polycrylic and then two coats of Flex-Coat stone mason roof coating I got at Home Depot .. let it dry for at least a week or the Flex-Coat won't be fully waterproof yet. There is also a product sold on your side of Canada

that is claimed to be totally non-toxic, environmentally friendly, etc, etc., but they are charging about US$100 a gallon for it. .. yikes!
