VHT Prime Coat is a unique, multipurpose formula designed for use on metal, fiberglass, wood, and most plastic surfaces (see 'selecting a primer' below). These primers are excellent foundations for any enamel, acrylic, epoxy or synthetic lacquer finish paint products. VHT Prime Coat air dries quickly, provides a rust and corrosion resistant barrier that allows for excellent adhesion for intermediate (color) coats and top (clear) coats. VHT Prime Coat can be sanded for multi-layer buildups. Multi-layer build coatings optimize smoothness on flat and contoured surfaces.
