Hi all - I can't find an appropriate thread to pose this question, so figured I'd start one. My apologies if it's a dumb question: I'll be replacing all the plywood backing in my seat boxes, side panels and sun deck as mine is completely shot. The boat sat under it's not all that great fitting cover, but otherwise open to the elements over a winter and rain had ponded in the middle of the cover creating a tremendously humid situation underneath. The end result is, everything wooden on this boat is shot. My question is - How do I treat plywood backing to prevent moisture from getting in while still being able to staple the upholstery to it? I figured I could coat it with resin first, but I'm afraid if I glass it will be too hard to get a staple through and it would likely crack anyway? Any suggestions? I've replaced the sun deck plywood once before and would really like to make this attempt the last one. Any and all input would be greatly appreciated.
