rust proofing
I have always gotten all my new vehicles rust proofed. I'm wondering if I should do it with my new 2022 F-350 if it is an aluminum body. How many still do this with their trucks. My last two trucks were used.

The frame and other bits are steel and only lightly protected. Aluminum can corrode, but not in the same way as steel. Unless it suffers contamination or electrolytic damage, it's not likely you're going to "rust" the body. Me? I don't do anything since even bare steel rusts so slowly here that whenever I see a rusty car, I know it's a northerner.

Usually, when you 'rust proof' your vehicle, I've always seen it referred to as coating the frame and has nothing to do with the body (except maybe the body mounts). Frame is still steel and will rust. For me, rust proofing is running it through an auto car wash on the warm days during the winter. I don't mess with coatings until I see rust of flaking, then I'll dress the impacted areas and rattle can them.

A mix with motor oil and Bar & Chain oil. The oil thins the B&C enough to spray it easier. Normal road grime attaches to it and makes a dry tough coating on it.

That would be an excellent idea if the DW would go along.

It requires you to crawl under the truck once a year, it's not a one time application, you have to reapply annually. They have a newer formula that supposedly lasts longer, but it will still needs reapplication. It's good stuff, just not for everyone.

I prefer Woolwax and had both my new vehicles coated within a couple weeks of deliver here in MA. FluidFilm is also good. The lanolin based products have a distinct advantage over the petroleum ones(Krown, etc) in that the smell is almost unnoticeable. Up North, it's a lot more than just the body rusting through. It's every fastener on the vehicle becoming so corroded the head rounds off before it even thinks about coming loose.

When I bought my new F250 I mentioned I wanted to get the bed sprayed with bed liner. They recommended LineX. I asked some questions and they also mentioned that the local LineX shop also undercoated vehicles.
I decided to go with both, bed and undercoating. Made the assumption that the undercoating was as good as the bed liner material which is pretty darn tough and lasts seemingly for ever. But I really have no idea how good their undercoating may be. The bottom of the truck/frame sure looks pretty though.
