You can also use just about any white lithium grease. You can find that in the automotive department, like at Wal-Mart.
Ha! I thought I was the only one who uses this... I've had gun snobs talk smack about using an automotive grease on guns before, but it works great and is cheap. I also like to apply CLP to one surface and moly grease to the other sort of like Outbreak said. Everything feels super smooth doing it this way.Go to the local auto parts store. Pick up some moly wheel bearing grease. Works just fine.
