Developed by The Boeing Company, Boeshield T-9 Lubrican/Protectant is a superior lubricant and protectant. Based on a unique combination of solvents and waxes, Boeshield T-9 penetrates metal pores and dissolves minor corrosion, leaving a resilient waxy coating that lasts for many months. Ideal for the tough saltwater marine environments, T-9 lubricates and protects all metals. Boeshield works well on engines and deck hardware as well as electronics, batteries, and wiring connections. Boeshield T-9 is nonconductive and will not cause short circuits. Wont harm paints, plastics, rubber, or vinyl. Attacks existing corrosion, loosens rusty parts, and protects all metals for months. Use on bicycle chains and woodworking tools, too. Made in USA. Cancer and Reproductive Harm- www.P65Warnings.ca.gov.
