Did you just put the resin over the plywood, or did you use fiberglass sheets as well?

Some areas, corners and seams have matting with the resin, the rest of the surface has just resin. I did forget to mention, that I put a coat of Gel Coat on top of the resin. (whoops sorry) Anyway, what this is basically the same construction as a boat hull. gel coat ontop of fiberglass ontop of wood. This will last for quite some time. Some of those boats in the harbour have not had any hull work in years and they take a larger beating than your tank will and they are still floating!
