Designed to be used a lubricant to apply to potential wear surfaces before assembly in order to prevent metal contact upon startup before adequate lubrication is supplied. Provides three times greater film strength than conventional black Molybdenum Disulfide greases and will not clog oil filters. This product clings to all surfaces and is an excellent rust inhibitor, allowing the storage of parts for years. A thin film of protection is all that is required on mating parts. Red Line Assembly Lube will mix with our motor oil and can be used on all lubricated parts such as cams, followers, pistons, and bearings, and bolt threads. Use only a small amount on bearing and piston surfaces – too much can make it difficult to turn over the engine. Red Line Assembly Lube is an excellent corrosion inhibitor and can be used on machined surfaces to provide long-term corrosion protection. Do not use on exhaust bolts or other high temperature bolts which require an anti-seize.
