The Boeshield T-9 Lubricant dries to a thin waxy film that clings to metal for months. These properties make it ideal for bicycle chains, particularly in wet environments. Boeing also successfully tested T-9 in marine saltwater environments, and it protected against corrosion caused by the salt. It will also loosen rusty and corroded parts and is safe on paints, plastics, and vinyls. This quality lubricant comes in a 4oz. container that is easy to apply to any drivetrain.
