I am building a 8'x3'2' tank, about 400 gallons. It will have a 2x4 frame and plywood on the inside (obviously). I have a pond liner, however I do not think it is large nough for my application so I am thinking of rubber coating the pond instead. What rubberized coating should I use? Is it something I can find at Lowes/Home Depot? Or do I have to special order it? Also, what do I do with the seams, will goodstuff foam allow rubber coat to stick to it, or should I use something else for the seams? Any help would be greatly appreciated.
