What's your favorite lube and corrosion inhibitor

Mine is Corrosion X: http://www.corrosionx.com/corrosionx.html

I use it on virtually every articulating chassis hinge on SpongeBob. It's great for the exterior basement door hinges and latches as well as the engine door. I use it on all joints where chafing, humidity, road chemicals, and the elements can start corrosion. I bought a gallon 5 years ago and I have plenty left. A drop goes a long way. It polar binds to the metal substrate and capillary action ensures that it diffuses evenly. What's your favorite?
