They use some liquid with molasses & some other stuff round here (Vernon, British Columbia) when it isn't too cold. That stays on the road when put down before snowfall rather than flying off like the salt.

No idea what molasses do for rust though.emoji848.png

We just got a good rainfall the other day, it was badly needed to remove some of the salt residue on the roads. It looks like winter is almost over where I am, although you never know...last April 15th we got a few inches, and of course the road brime and salt stayed around until May.

 

I really am kind of on a quest to keep this truck "rust free", or close to it. How long I'll be on this kick I don't know. Lol. But right now I'm still hot on it. I'm actually excited to get under it and clean up some spots and apply another coat of protection. I think I'm getting really weird. I go through these fazes.

I have a 2015. I live in MA, made a point of washing off salt during the winter months, didn't do much good,  29k on odometer frame is rusting, it's past the 3 year bumper to bumper so I guess I'm out of luck..

It's only cosmetic but i do agree it looks poor when it browns up and flakes off leaving rust patches. Gm has been this way since i started driving back in the early 90's, all my trucks after a couple years living in mass also have turned that way with the wax coating they have used for decades. One thing though at least i have never had a single issue with frame rot, rust yes but not rot thankfully.

What does everyone do about winter prep for the trucks? The wax is slowly falling off of mine. So I was thinking of cleaning it then sealing it was a rust prevention chemical and then reapplying the wax again? Is that worth doing or is better to paint the areas of the frame I clean with actual paint?

The wax is useless IMO.

 

If you prep and apply a protective coat (1000s of options), combined with spray on rust-inhibitor - I think you will have the best results. The rust-inhibitors can be wax based, or oil based. Some have negative results due to the oil in them, which tends to swell different types of rubbers. Hoses and grommets and bushings are places to avoid the oil-based ones.

 

The main points where the rust starts to form will be edges, bends, or the points where the lift contacts on the chassis. The tubular support going through each chassis rail is a very susceptible location.

 

You will not fully prevent rust, just slow the process. So dont get too frustrated with rust. It will be an ongoing process for the life of your vehicle. However, there are lots of ways to manage and reduce the rust, focus more on those!

I'm having this issue right now too. 2016 with 50k km. Thinking I'll just get the whole frame redone down the road. Surface rust won't hurt anything.
