Thinking about building a wooden enclosure for a BRB, have a couple questions. 1.What is the best way to waterproof the wood? Ive seen a few saying to glue linoleum or acrylic to the interior, but couldnt find acrylic sheet rolls(paperlike) at home depot... Seen a few about staining and painting; dont like this idea. A build on here was talking about using melamine wood and then there would not be a need to waterproof. Is melamine waterproof? 2. Can heat pads be placed on acrylic sheets(glasslike panels), or would it be better to buy glass? Want to cut a hole in the bottom of the enclosure and attach the undertank heater there. Dont like the idea of putting a heat source on wood. Any suggestions?
