Valspar's Flurothane Coastal coating system, a polyvinylidene fluoride system developed for use in extreme coastal environments, uses a thick-film primer application, which allows it to be used in the harshest climates. The coating also resists ultraviolet rays to retain color, according to the manufacturer. The system can be applied to hot-dip galvanized and aluminum substrates for use with metal roofs and wall panels.
