Does this make any sense whatsoever for people who don't wash their own car at home?
Imagine a car-care-conscious person who has access to garage parking, cleans their windshield wiper blades to extend their life, and removes bird droppings with a damp towel as soon as they happen... but doesn't have access to a garden hose and so must use touchless automatic washes every few weeks.
Are those automatic drive-through washes, even touchless, just going to wreck the coating fast?
Talking about a semi-nice compact daily in an area that sees harsh winters with lots of road salt. Think Audi A3.
