Rams with rust
My 1995 dodge is just starting to show rust on the right bedside above the tire.
It was under coated when new and has been kept inside for many years now
But have had to change the transmission cooler, fuel and brake lines, fuel filler tube all due to rust
Took the wedge shape shell off so I could go thru the car wash and get underbody wash. Try and do it after every snow when I drive the truck.
The Brine solution that they think is so great is what is causing the vehicles to rust so quickly, plus all the salt
Go to areas that do not use salt and they do not have the issues
The manufactures are trying to make them better at preventing rust, but you soak metal in salt water it is going to rust.
The best solution is to try and clean it was soon as possible after driving in the crap. Even if it means washing it a few times a week.
Keeping a vehicle in a warm garage also speeds the corrosion as the salt mess melts and drips off the vehicle it attacks the metal quicker.
