urethane foam core and peel ply on the cheap

[bly]

It glasses good and all. I did use it more for insulation then structure because I laminated it to the underside of my new coffin lid I built. But the bottom is just a thin layer of glass facing the coffin inside. Now the best. No epoxy needed! Since it is not styrofoam it holds up to vinyl ester and polyester resin contact. I have also been thinking about replacing the wet foam flotation that I removed from the 20 sea craft I am doing with some of that foam only the thicker stuff maybe in multiple layers. For flotation only. I am thinking of blocking it up off the bottom with pieces of scrap penske under. Then laminating all the edges with a layer of 1 1/2 mat.
