People tend to over rate the effects of under coating. There was a day and a time where it was indeed necessary. But Honestly with new vehicles I think it is a waste of money. They do so much treatment of the metal at the factories that things hold up fairly well.

Beside which to truely be effective you have to have these oil treatments done on a regular basis.....

Now if your really serious about this, what you need to do is find someone with a Line-X dealership, that wants to be experimental. Take the body off the frame, coat the frame with Linux, and the underside of the cab and bed as well. Put it all back together and you will have something worth while.
