So I am currently in the process of planning a plywood aquarium build and was planning to set up the viewing panel as glass silicone to Pond Armor. I was just wondering if anyone else has done this and had it last long term. I know the King of Diy recommends this stuff but I was talking to a guy who has apparently been building plywood aquariums for years. He said that silicone wouldn't stick to plastic long term. He basically said you could get maybe a year out of that stuff maybe if you're lucky. When I told him about Pond Shield he didn't know what the product was as he's probably a bit of an old timer. Any thoughts? Would silicone stick to expoxy or would it eventually loose grip like he said?
