i didnt want to screw into the sealed floor under the gas tank, so after careful marking. i dunked the pieces into the epoxy, then layed the pieces of wood in a puddle of epoxy. followed by a generous amount of resin with thickner/fibers all around the sides and back. after there was a nice tack in the front of the pieces, i stuck the foam strips on them. the only screws will be on top of the pieces to secure the tank.
