I am putting a new plywood floor in my boat. It sounds like a lot of guys epoxy the plywood to seal it up and protect it from the elements. What kind of epoxy do I use, where can I get it, and how do I apply it? I have never used epoxy before, so this is new to me. Thanks for any help.

I get all my wood spray in bed linered it pretty cheap on wood cause they don't have to prep it and it makes it pretty much water proof
