Has anyone ever tried to use thin plexi to seal a ply tank? Another material that come to mind is some stuff called coraplast (or something like that), it's basically a plastic cardboard. I've had some signs made out of it and it seems pretty water proof. I'm just thinking that a solid sheet of something would be more reliable than painting stuff on the plywood.

The problem with extruded plastic products is that they shatter or split under pressure. Thin cell cast acrylic might work, but why line a plywood tank with something clear when you could build an entire tank out of it?
There are better solutions for sealing a tank. Either build an acrylic tank or seal the plywood appropriately with something like Pond Shield if you want epoxy or Pond Coat/Rubber Coat if you want a product with elasticity.

I used 1/4" plexiglass about 17yrs ago to seal a plywood tank. I used aquarium silicone to seal the corners and viewing window. The tank held water for about 4 years until a leak unrelated to my silicone job rotted the bottom out of the tank and I took it apart.
