Im trying to replace the two flooor side pieces and the center piece with fiberglass what kind of material should I use?, how I bond the two side pieces with the existing floor thanks for the help.
yes they factory the center is the one for the gas tank I really never used them and I want to put carpet on the floor that is the reason I want to close them with fiberglass.
if you want to carpet it just cut plywood to fit the openings glass both sides of the ply to seal it and carpet over the top if you make the carpet removable (like velcro it down) clean up is easier and you could still use the hatches
Cut up some Marine plywood, then glass over it. Read a few pages of Oops! hull extention thread...All the answers you are looking for on glassing are there....
