Default Prevent Rust on my new Ram!

I just recently purchased a new 2014 Ram and want to protect the frame and underbody from salt before winter starts. That being said I'm stuck between Rustoleum undercoating spray and Rust Bullet Black Shell to do the job. Does anybody have any ideas or what have you used? Thanks.

5 years of MN winters and there is nothing but surface rust. I wouldn't waste any time or money on it. Didn't have any trouble getting the shock bolts loose a couple months ago if that is any indication. It does help that it sits outside year round and I rarely wash it in the winter. If you keep it inside or run it through the car wash a lot in the winter then you will see a lot more rust.

Oh how I don't miss the New England winters and the salt/sand on the roads. Anyhow, I would suggest normal washes with undercarriage blasts during that time of the year.

Eastwood's rubberized undercoating is what I used....7yrs ago. I bought the bulk cans and their profesional spray wand and used a compressor. I taped and bagged off all the components and sprayed 2 good caost on everything inclusing the backsides of the rear quarters. I used 3.5 cans. I think they were 32oz cans??

I regularly spray underneath the truck in the winter as well.<----big help.

Here's what underneath currently looks like.

DirtyDog, how many winter miles has that been through?

Oldtimers always preached spraying the undercarriage with boiled lindseed oil.

I traded in my 06' with almost 170k miles and brutal winters here with TONS of salt. While my doors and rear fenders were rotting my undercarriage looked fine. Just surface rust and not an ounce of heavy scale that was weakening anything. I bought a case of Fluid Film to spray my door and fender interiors this winter with to hopefully avoid body rot. But as for the undercarriage i would not be worried about it.
