Dupont "Teflon Multi-Use Dry Wax Lubricant" AKA Dupont "Performance Dry Multi-Use Lubricant with Teflon"
This is from the Performance Lubricant line from Dupont. It dries to a non-sticky film that will remain in critical areas of the chain longer than anything I have ever found. Dirt does not stick to it. (teflon is a non-stick coating too).
DO NOT GET THIS STUFF INSIDE YOUR CLUTCH OR ANYWHERE NEAR YOUR BRAKES. Teflon is slippery. It goes on as a watery liquid that dries very quickly. After application, give it a few minutes to dry before running and it won't sling off.
I have found it at Lowes, and O'Reilly's Auto Parts.
