The inhibitor protects and preserves metal surfaces, electrical connections and engine components and fasteners that are subject to saltwater spray and high humidity. CRCs Heavy Duty Corrosion Inhibitor also provides effective protection for steering and throttle linkages. Size: 10 oz. can. Cancer and Reproductive Harm- www.P65Warnings.ca.gov.
