Marine plywood VS. pressure treated (wolmanized) plywood
I need to rip out and replace the plywood under my cockpit floor. Since marine plywood is expensive, and hard to find, I was wondering if using pressure treated plywood (for outdoor decking) would do the job. Please correct me if I'm wrong, but I thought the only real difference between marine and regular plywood is that the marine ply used a non water soluable glue, and regular ply does not. Now for the assumption (yeah, I know), wouldn't pressure treated plywood also use a non water soluable glue, AND also have the pressure treatment to make it withstand rot even better than marine plywood? This is my thinking for using the pressure treated as opposed to marine plywood. If I'm wrong, PLEASE tell me before I make a mistake. Thanks.
