For those who cry for different materials, don’t think for a moment that anything is impervious to salt. It’s like driving in battery acid.
Actually, that is not true, as Salt (road salt, or halite—sodium chloride containing mineral impurities) is chemically neutral. It is neither basic, nor acidic. As you illustrate, it is however able to react powerfully with a variety of substances, including those used to make Mopars.
From the perspective of Joe Average, however, your point is well made.
