Fluid Film AS11B is a penetrant and lubricant formulated for corrosion prevention and rust protection across automotive, marine, and recreational vehicle applications. This non-toxic, long-lasting liquid has proven effective in highly corrosive environments for over fifty years, from offshore drilling rigs to salt-laden marine vessels. It penetrates existing rust on contact, stops further corrosion, and creates a protective barrier that creeps into tight seams and chassis crevices to shield metal from salts, brines, and industrial atmospheres.
The product’s self-healing liquid barrier will not chip or crack, ensuring durable protection for vehicles, equipment, and metal parts exposed to harsh weather and corrosive conditions. Whether you’re protecting an automotive undercarriage, marine hull, RV exterior, or salvaging frozen bolts and corroded fasteners, Fluid Film delivers long-lasting corrosion control without drying out over time.
