The RN used it on just about every aircraft to prevent corrosion, in the 50s through to the 90's. Thats a long time if, as you feel, it doesn't work!Other than a means of degreasing, I have never found WD40 to be of little use for anything. I certainly know from using it on my woodworking tools and machinery (my trade) that it doesn't prevent corrosion, and doesn't act as great lubricant either. It is a brilliant product for cleaning bathroom chrome etc though.
I prefer either Triflow TFL200, Duck Oil or ACF50.
We were MOST happy with the results!
But the secret will probably be in the WAY it is used, a right way and a wrong way....
You should also have a look at the WD-40 website, you can learn a lot there....
