I had a '97 4Runner I bought new, and drove on salt encrusted winter roads for 22 years. No rust when I sold it and bought a 5th gen.
No special undercoatings or treatments, I just washed the salt off whenever necessary.
...and to OP,
would you consider fluid film?
how is your 4runner now?

Where are you? I'm in Ohio, and my 2001 rusted into undriveability at 265k miles. But then, I was never religious about rinsing underneath. If you were, and that kept yours in good shape, that's encouraging.I had a '97 4Runner I bought new, and drove on salt encrusted winter roads for 22 years.

How are your splash guards are they in place? Where you live I'm sure they use salt/chem on the winter roads and if you drive it often in that stuff, thats what you'll get. I have an '03 that doesn't look that bad in engine compartment but is has a lot on the undercarriage that I battle constantly. As has been said give it a wash in the winter when you can and in the spring take it on a couple of long drives when its raining heavily.
Yes, the splash guards are in place.
I live in Northern Ontario and the City use a lot of salt during the winter. Daily! We have temperatures down to -30C and there is no way to wash the truck.
But as I wrote, my wife's Escape is one year older, way better quality, there is not a hint of rust and she drives the same streets.
That's pretty wild on the Escape, but nice! People a few doors down have an Escape, don't know what year and it has external rust showing, go figure! ....But I HATE rust!
2015 in eastern Canada.
We have indoor wash bays here, which I use very often in the wintertime. I also use an undercarriage "water broom" on my pressure washer in the summertime. I also keep the engine bay clean.
I touch up the underside every spring and fall. A bit of fluidfilm here, a little black rust paint there. I usually tidy up the front during an oil change
Everything looks great under my 4runner
OP, do you park your 4runner in a garage vs the Focus being parked outside? I lived in IL for many years and in some cases when you park a salt-covered car in the garage it makes for a warm and humid environment, which heavily promotes rust. Parking outside in the cold is better in that scenario.
i agree with this, don't park inside your garage in the summer time, the humid air doesn't help. in the winter time, ok to park inside since the air is dry but wash your car first.
