Graftobian Special Effects Wax Sealer is a flexible collodion product used to create a durable skin over FX modeling wax formations. Use three or four coats of fast drying FX wax sealer to prepare even a soft wax surface for brush or sponge application of makeup. Special Effects Wax Sealer is very comparable to liquid latex but it dries a bit faster. You can even put texture into the fx wax sealer by pressing it with a stipple sponge after applying the first coat.
