100% agree. I'm no chemical engineer or metallurgist, but I know if folks would just take the time to pressure wash their chassis (even during) the winter, you will lessen the corrosive effect of brine/salt. Unfortunately, most people do not and will not do this, let alone keep their car's paint and interior clean. It won't stop it, but will hasten it. If you want to prevent it, one should treat their chassis with an oil treatment (there are some out there, google it) every winter season. This is what I plan on doing when I eventually purchase a new car/suv.
