Minnesota is bad. My next truck will be from socal or the desert.

LOL. There were some areas of the frame that had completely rusted through, just the photo doesn't show it...It got worse when I got under!

So why is the NE worse for this? (And parts of Canada?) More days below freezing temps? Do some DOTs use different chemicals? I mean, states like Colorado, Wyoming, Montana, Idaho get plenty of snowfall as well. Is it a problem there as well? Or just not as bad? https://en.wikipedia.org/wiki/Salt_Belt

I've only lived in SoCa and here, so I've never seen this. I've traveled SW and SE of the country, and only a handful of times up North, but never paid attention. Occasionally, you do see Northern cars driving around here. You really pick up on the white ones, LOL. Just curious...

I think it's because those areas also have higher humidity year round as well as rainfall. A lot of factors are at play though. It could have been a bad day on the pretreatment line, the truck was used to plow & spread salt, never washed/rinsed after salt exposure, kept in a garage after salt exposure, had undercoating applied (really, all ANY of that **** does is trap moisture and make it rot faster, despite looking black), ect. Toss in the mix some bad engineering where water gets trapped (like a rocker panel) or a drain hole gets blocked and bam- rot holes. Those are what I believe are the major contributors, salt being the common denominator.

a lot of it comes down to what was used, how much was used, how long of a stretch was it being put down, how long before the town cleans the roads of the residue, did the owner even wash the vehicle?

@ the quarry that I used to work @, we had the following for sale:
straight sand
straight salt (white, pink, & blue)
(the diff colors are diff cost & diff aggressiveness)
straight calcium
80% sand/20% salt
50/50

the towns around here have diff requirements.
the landscapers/plow guys have their own preferences.
sometimes a storms forecast will dictate the use of a diff product.

Up in the mountains CO gets snow, but the more highly populated areas of Denver, Colorado Springs, and Pueblo don't get **** for snow. Yes, they use harsh chemicals on the roads, but when it melts and falls off the next day it's just not as bad as the NE where is stays frozen, clings to your frame, and the roads stay covered pretty much nonstop.

A lot of the smaller mountain town and more rural areas use sand/gravel instead of chemicals too, which obviously helps. They use salt at most of the stop signs and steep hills here, and all over in town. It just gets worse the farther east you go from what I've seen.

They used to use dirt here in the Springs when I got here in 2010 but they've since changed to a brine solution.

I live almost DEAD CENTER of British Columbia on the west end of Canada. Corrosion is a reality in a world where melting the snow with salt is used to reduce snow to water instead of plowing it away or driving at a reasonable speed.

The consensus here is that an indoor garage creates an environment where your vehicle is kept warm all winter so salt and cathodic reaction are enhanced. To reduce corrosion on a daily driver a carport optimal. Car body is kept colder, corrosion is SLOWER (sadly, corrosion still progresses).

Very important to prevent or wash away the buildup of salty slush in the winter and mud in the summer. Clean water corrodes far less than salty slush. (Or calcium or any other "snow melting" media applied to roadways)

I want to have an underbody pressure washer in a heated shop if I find my way back to the rust belt.

Here's my 88 from Los Banos CA (88 - 08) and then the desert in AZ (08 - present). Never been touched. I used to live in the "Rust Belt" (WI) - never again, LOL.

I work for NYSDOT, they have a clear road policy. If it snows, salt, if it's raining and below 37, salt. Only thing we don't do is salt dry roads. And it's pure salt. On a bad storm put down 350lbs per mile or more. Drivers are idiots, they don't slow down when weather gets bad, and the state caters to them. Heaven forbid someone gets in an accident when snows on the road, they will sue the state for not clearing the road.
