I have seen forums just like this one but they never actually have any solid answers. My uncle is great with carpentry and things and he has wood so he helped me build a cage for my Savannah Monitor. He used some sealant on the inside "flexseal" it just seams toxic to me and I cant find a a solid review on it so if anyone has used it let me know. But that is not really my question. I'm most likely building a new enclosure with safe sealant on the wood. It needs to be able to handle high temps and humidity. I've thought of using polyacrylic which is a water based hard seal. I have read however that contains bad chemicals. Any feedback on it? If anyone knows of something to keep the wood from rotting and leaking, letting me know would be greatly appreciated.
