Heh heh, hey...I can contribute to this thread too
My summer job in the '70s was new-car prep at the local dealership...with a rotary and wool pads :soscared: Yep, I was "that kid with the rotary". Actually, I did OK and was the only guy allowed to do dark cars (wonder who did 'em when I was back at school :think: ). That was in the days of single-stage, which I found easy enough to do OK on, at least by the standards of that time. I should note that I had my own set of pads, products, and towels that I took home every night

I still remember how heavy that Milwaukee felt...
When I realized that I had to get serious about college, I got rid of my (oh-so-nice) black car and got a beater, which I simply ran through the carwash! Yep...I just treated it as a disposable car, pure transportation. And when I traded it in (after a quickie detail) I got just as much for it as I woulda had it been perfect.
Did the same sort of thing with another car a few years later when life had me too busy to keep all the cars perfect; I'd run it through the local carwash (at least they have cloth strips instead of brushes) every other Friday and I'd detail it sorta-properly every few months. Yeah, it looked like [crap] compared to my other cars, but when I traded it in they gave top-dollar (heard him on the phone saying "you won't believe this thing, it's showroom-new..").
I ran some family cars through the same carwash as recently as the late-'90s. I'd tip the guys at the dry-station a little and they'd spritz it down with QD before drying it with my MFs. Worked OK...the owners were satisfied.
Other...."normal"...people simply don't notice or care about all this "Autopian-level" stuff.
