Red Line assembly lube is designed to be applied to potential wear surfaces before assembly, in order to prevent metal contact upon startup before adequate lubrication is supplied. Red Line assembly lube will mix with the oils and not plug filters. It can be used on all lubricated parts, such as cams, followers, pistons, 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 this lubricant on exhaust bolts or other high-temperature bolts which require an anti-seize.
