Fubar5, watch your language! Don't use the "WD" word around me! Untill recently, their label said that it did all kinds of wonderful things, but one thing they did not claim to do was lubricate! They have since added this word, but I don't think they changed their product any.
A friend of mine used to call WD-40 the locksmiths best friend. A lock would get stiff, and people would squirt it with a little WD, and it would (temporarily) work smoothly. But, after a short time, the acitve ingredients (alcohols) would evaporate, and the lock would then totally fail, and my friend got to sell a new lockset!
For displacing moisture or stopping a squeak, it works fine, but I personally would not count on it for real lubrication!
Just my humble opinion...and of course, I could be wrong!
