Here I got the swim platform glued down with epoxy resin thickened with cabosil and glass fibers (rice pellets). Placed a foam block around the top edge so there would be more surface area for the platform to sit on and glue to. After the epoxy set up I tabbed the tub to the swim platform inside and out. In the inside I wrapped the foam and tabbed to the bottom of the platform.
