The holy grail of penetrating oil !
Ok, I don't know if this is the right place to talk about this but I realy need to share this experience (my generous nature).
I have used many diffrent types of these over the years and was always left in doubt. Lastly I found myself using PB Blaster. But my faith was reborn after using something the airline company I work for uses: Mouse Milk ! Yes Mouse Milk : http://www.mousemilk.com/index.html
I don't know if anyone other than me has ever had experience with this stuff but wow I am conviced.
Well that was my latest discovery and hope It helps.
