I live in the United States and never heard of a rust proofing option either, and I live in the wet PNW. It’s a big republic separated into 50 individual states. There’s a lot of variance; some places have hustle but most don’t.

It's not about wet, it's about salt. You're on the wrong coast to have to think about rustproofing. Rustproofing is less necessary on modern cars than it used to be, and dealer rustproofing is pretty much universally worse than third-party (RustCheck, Krown, Corrosion-Free, etc.) but if you drive on salty winter roads for 1/3 of the year it definitely helps things not rust out on you as soon as they would otherwise.

  This is incorrect. Rust is a reaction of iron and oxygen. Salt accelerates the process because it is ionized, but not necessary. You can flash rust pure iron in seconds with distilled water. Furthermore, ice alone is basically inert at the timescales that we experience. It would take eons for pure ice to react enough for visible rust to form. Even if it was cold enough for salt water to freeze, the difference would be negligible because salt and water separate from each other as the water crystallizes into ice. Also, we salt the roads here. Our freeze/thaw cycle is more frequent allowing for rust reactions to occur throughout the season, whereas a colder climate will only see reactions in the spring. There is no shortage of rust here.

Yes, sorry - I was in a flippant mood and generalised a bit :)

Only the higher elevations in the PNW get snow, and I don't know how much salt the highway departments use. My wife said that when she moved from upstate New York to San Francisco, the first mechanic she took her car to asked whether she drove it to the beach a lot. He was not used to seeing the effects of road salt.
