Loos like we Yamaha guys are having a lot of fun doing this!! Smh
I might just lay-in my plywood and discard my old cap( the bottom layer of fiberglass) and just make the new glass tight as can be

I really wanted to just fill it with resin then drill out the holes and avoid wood all together.

I almost did that. It was a pain to get it flat and it kept wanting to curl. This is also the bottom side so you don’t even see it most of the time.

It would not be cost effective to fill the whole thing in with epoxy in my opinion. You need to put some sort of solid core in like wood or fiberboard. As it was I used almost a gallon of epoxy just attaching things together.
What you could do is put a solid core in, cover it with epoxy and then paint the bottom.

Why wouldn't just a sheet of rot resistant green treated plywood work? It's half the price and can be found in 3/8 thickness?
