Vehicle Undercarriage - Rust Coating & Prevention

Editor's Note:
I just applied some of this "Fluid Film" to the underside of my 20-year-old Ford pickup truck and I'm very happy with the results.  You may have heard about folks who spray used motor oil on the underside of their vehicle to stop rust, and it works, but it's dirty.  This "Fluid Film" is a non-toxic alternative that anyone can put on their vehicle.  Unlike traditional undercoating, this is a light coating of oil that penetrates and protects your vehicle if it's already starting to rust.  If your car is brand new then I would suggest rubberized undercoating.  Otherwise Fluid Film is probably the way to go!
