While I do agree that modern cars are somewhat protected.. the use of brine on the roads as a deicer changes the game. Brine solution use magnesium chloride instead of sodium chloride (rock salt). It eats metal like nobody's business!

As an Mech Engineer, I did a lot of research and ultimately went with NH Oil Undercoating for my 2017 F-150..... its essentially mineral oil mixed with graphite. It works amazingly well! It cost approx $200 for first app, and they get you $100 for a reapply every other year or so. They pulled off all the frame plugs and sprayed inside the nooks and crannies, rocker panels etc etc.
