I have a wellcraft boat, I noticed a soft spot in the floor and decided to investigate. I eventually took up all the fiberglass on the deck to get to the plywood. After all was said and done i need to replace the floor. The stringers are in good shape. So my question is, I have heard of encapsulating the wood. If i put resin on bottom and fiberglass on top, can i use regular 3/4" plywood? Or do i need to use treated? Or instead of encapsulating the wood can i put an oil base primer/sealer on the bottom and lay fiberlgass on top? I've searched a couple forums but i can find out these exact answers. Thanks in advance for the help
