Hot Wire Foam Factory recently introduced their new Styroplast two-part coating for all foams. When mixed you have about 12-15 minutes of working time and when cured the coating becomes fire-proof, water-proof, and hardens to protect all foam surfaces without adding a lot of weight to the foam. The possibilities for use are extensive and Styroplast can be applied with a brush, trowel or sprayed. For anyone that hot wire cuts foam, the finish can be greatly improved with a coating of Styroplast that can be sanded and painted to a beautiful finish. $29/quart
