It also can illustrate how easy it is to use this foam -- it cuts so easily and shapes so well that piecing it up doesn't add all that much time to the project. This foam is available in thicknesses from 1/2" up to 6" thick at any fiberglass supply house. You can also use the polyurethane insulating foam that is available from building supply stores. Just peel the foil layer off. (Keep in mind that styrofoam won't work under any resin with styrene in it, unless you can bar the resin from it.) | It also can illustrate how easy it is to use this foam -- it cuts so easily and shapes so well that piecing it up doesn't add all that much time to the project.
