Why is that? Unless the word has a different meaning in the US, "Marine" ply is actually untreated and made with a special glue that can be softened with heat so the ply can be curved to shape a boats hull, and is just a big fat waste of money for this kind of usage. You would want normal ply but H3 treated if its going to get wet, either that or paint and seal it well.

Sorry about the confusion. Here it means the plywood is treated to resist moisture.....waterproof so to speak.
...you're both right, to a certain extent. Marine ply, even that sold in Aussie or NZ, is pretty much water proof, and good for building decks, boats or (luckily) fish tank stands. The faces are coated with a resin finish, whilst the glue used is an A-bond, so pretty mmuch waterproof also. I've not heard of marine ply being heated for bending, but that would make sense, as soaking it would be pointless... As for the H3 gear...thanks to all the "experts" out there who know two fifths of F.A. about timber or timber treatment, H3 (as we know it in the traditional CCA form) is pretty much outlawed in both countries (Aus and NZ, no idea of the US, though). Although you can still get it in landscape form, any Greenies within earshot are guarenteed to give the death stare...
