KBS Coatings Cavity Coater is the perfect solution for providing rust protection in hard-to-reach areas. Cavity Coater is a single step, super-penetrating corrosion inhibiting coating (CIC) designed for long term protection of all metal surfaces. It provides a self-healing film tested to render more than four thousand hours of salt spray protection; over 4 times the protection of conventional cavity waxes. Cavity Coater can be used to protect the inside of frame rails, rocker panels, fenders, quarter panels, doors, tailgates, windshield cowls, posts, and more. Cavity Coater wicks into welds and seams that primers and topcoats can’t reach. Cavity Coater resists road salt, alkaline solutions, and chemicals. For especially hard to-reach-areas the Cavity Wand is offered to extend the reach of aerosol Cavity Coater with a reusable 48-inch hose that features a 360-degree spray tip. The Cavity Wand requires only a 1/8-inch hole to insert and is easily cleaned. Cavity Coater is available in quart, gallon, and aerosol versions.
