Hello, I've been planning a build for a while for my nearly 8ft female RTB and I've been reading that people are recommending pond armor as a good sealant. My question is twofold. One, if I used this in the clear form on plywood, would I first be able to paint the inside with regular paint, or does Pond Armor not stick to paint? If not, could I, at the very least, stain the wood? I hate the thought of leaving it plain, nor do I want the cheaper black pond armor/more expensive colored options. Second, if there are any other cheaper sealants that would make this enclosure 100% waterproof (thinking of one day putting in some type of water element such as a waterfall or little "Pool", but not just yet) and be non-toxic and go over paint/be able to be tinted. For perspective, I am making the closure either an 8x4x2 or 8x2x2 with glass front 'French type' opening doors and two locks on top and bottom. Also, while I'm thinking of it, I had planned to heat the enclosure with a CHE placed about 1-2 feet from the left of the enclosure and lighting it on the upper sides with LED rope lights. I was hoping this placement of the CHE would be good for reaching gradient heat levels, but with such a large enclosure, I'm not entirely certain one 150w CHE alone will suffice; especially if I make it 4 feet tall, but I think that might be a little too tall. I have read about flexwatt tape, and thought about putting it on the bottom, halfway across so that there's a cooler side, then laying down a sheet of vinyl or laminate boards. Any thoughts on the heating as well? And if anyone has any opinions on which size would be best, let me know because I can't really pick. It's either going to be 8x2x4 (LxWxH), 8x4x2, OR an 8x2x2. I'm leaning more towards the last one, but just not 100% yet. Thanks!
(Sorry for all the questions, first time building and I want to make it perfect the first time, and have it all planned down to the tiniest detail before doing anything.)
