Larry And a very good opinion it is for porous foams. Thank you. When using the stryrofoams with their increased density and surface smoothness, which smoothness by the way is made less so by hot wireing and 36 grit sanding, I find that the first wet layer is the bonding layer and the following slurry is the weave filler. I use styrofoam simply because it is convenient and CHEAP! I would use urethane if it were locally available. I have in the past made some parts with the foil clad urethane sold as insulation, simply peeling off the foil. Very porous stuff and not consistently smooth under that foil.
