HydroArmor® 7740 is a sprayable, latex product that is designed for use on steel, aluminum, fiberglass, and plywood. This highly fire-resistant material can be easily sprayed onto overhead and vertical surfaces to seal joints. Heavy wet film builds can be applied without causing runs, drips, or sagging at bridge seams. Because this material is filled with hollow microspheres, this coating adds little weight to vehicle bodies, even at high film builds.
