Anyone try making a waterproof box out of rustoleum epoxy shield?

Trying to make a custom sized E&F table - thinking plywood with an epoxy shield coating might be the answer. Anyone ever try to use it for this application?

been thinking the same thing, at the moment just using thick black pvc sheet folded up at the corners. Interested in the plant safety of epoxy resin

I think I am going to try and use SmoothOn Smooth Cast 300. It dries to a really hard, white plastic (costs $85 a gallon)

I'll let you guys know how it works. Probably won't be any cheaper than buying an ebb and flow table, but for special applications (3' x 9' x 2" for a cloner) it might be nice.
