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!
You're exactly right Nebill. I've been telling people that for years. My Dad was on the Mo. State Highway Patrol, (retired now). Many years ago they used WD-40 on their service revolvers. Many of the office personnel don't fire their service revolvers except to qualify once a year. The WD-40 had dried up and slowed down the mechanisms so much some of them wouldn't even fire. Needless to say they don't use it anymore!
