Supposedly, marine-grade and exterior-grade plywood used the same adhesives. The difference is that marine-grade plywood has no interior voids, while for exterior-grade plywood a certain percentage of "void space" is allowed. I would think that a good exterior-grade plywood, with a couple-three of layers of penetrating epoxy on all surfaces (maybe a layer or two extra along the edges) would be as strong and rot-resistant as you can get. Slap a nice-looking treatment (wood "door skin", Formica, or whatever) on the exposed surfaces and it would look like a million bucks.
The "You're-full-of-crap" posts may commence ...... now.
Never forget them. Do something to prevent it from happening again.
