Chassis Saver, Grey, Gallon. A high solids, VOC compliant, single conponent chassis paint and underbody coating specially formulated to permanently stop automotive and truck corrosion without the use of primers or topcoats. Apply directly over tightly adhered rust after only marginal surface preparation using a wire brush and/or handscraper to remove loose scale and rust particulate. Optimum results can be achieved by sandblasting. Chassis Saver bonds to blasted and rusty metal to form a rock hard yet flexible, glaze-like, non-porous finish that won't crack, chip, flake or peel. Completely uneffected by road salt, gasoline, diesel fuel, oils, battery acids, hydraulic fluids, solvents, chemicals, or corrosives.
