>>yeah, i'm looking at doing oak vaneer plywood. i'm really doing it for the weight factor more than anything...



Hi Toon,



What sized cage or cages are you planning to build? What species are you building the cage(s) for? I may have some other suggestions for saving weight depending on the size of the cages and how many your are building.



>>Also, how many coats of a spar varnish should I coat the inside of the tank with? Or would a shellac be a better choice, being a fully natural organic compound?



Spar urethane requires a tremendous amount of patience to allow each coat to dry. You'll likely be smelling fumes for weeks down in humid Florida. But it does offer a nice degree of protection for the cost.



I'm not sure about shellac.



I'll go more into sealers once I hear more about your cage design.
