Red Line Assembly Lube, unlike other assembly lubes, will not plug filters after initial engine start up. Excellent rust and corrosion inhibitor, allows for long-term storage. For use on camshafts, lifters, pushrods, piston skirts, main and rod bearings, and bolt threads. Do not use on exhaust bolts or other high temperature bolts which require an anti-seize. Used by top engine builders, racing teams, camshaft and drivetrain manufacturers.
