KREEM FUEL TANK LINER is designed for use as a preventive maintenance product in metal tanks new and old; containing gasoline, gasohol, or diesel. KREEM TANK LINER has a unique formulation with extremely rapid set-up that prevents leakage from hairline cracks and seam pinholes by coating the tank’s inner surface with a fuel resistant elastomer. Not for plastic tanks. KREEM is NOT compatible with all fiberglass tanks. You must spot test before use. Read the Kreem “how to” brochure for detailed application instructions.
