Replace floor with??

I would hot coat the plywood and used thickened resin on the shell. I used a notched trowel to spread the resin on my hatches. I also used pieces of plywood rather than a full sheet. I cut my plywood to fit then I cut the piece into smaller pieces and left a little bit of space in between each piece. Then I forced more thickened resin in the joints and glassed over the top. I was very happy with the strength, we'll see how it holds up.
