I have my deck cut out and fitted into place. My plan if to cover it in 6 oz. glass and then filet it into place with epoxy, prime and then paint. It's made from 1/2" treated plywood. I have a question though. Using 6 oz. glass on the top and bottom, should I add a support beam underneath attached to the deck and floor for support? My plan is to ues the deck as a casting platform, yet add a small poling platform that can be removed when not needed.
