|i bought some white lithium grease from the hardware store.. 6 bucks for a 15oz|
*CHOKE* Holy Mary Mother of God..
Go read the orientation year article in ICDU. There's a place you can get a great lube (same stuff ICD factory uses) for WAY less than that.
... and since you're using White Lithium.. make sure you clean - and GOOD! - and re-lube more often than otherwise.
