Used motor oil lol. Smells like a 15 yr old vehicle but it was cheap. I know my grandpa used to do this up north because he wouldn't pay for Ziebart, etc. lol. You would need to reapply probably monthly on the areas that get blasted with rain/snow/puddles and the like. I only did it because I don't want a rusty underside on a Southern truck.Hope you had a good Thanksgiving there and that's good mpg for the trip! What did you use to oil the underside? Now that I'm not in AZ anymore I might have to consider doing this. They say winters aren't to bad out here but they do get some snow on occasion and I'm not sure what they treat the roads with.

I'd never buy a cheap imitation only the original!
