Insightman, thanks for actually posting that procedure. Reading that the first time I imagined leaving my Clarity at the vacuum cleaning station at the car wash, outlining those steps and their sequence to a 20 year old guy who barely speaks English. He's going to nod his head that he understands perfectly, vac the car and then forget what I told him about this strange automobile that he's probably never seen before. The manual makes it clear that the double N procedure must be followed but doesn't say what happens if it isn't followed and is hooked up to the car pulling mechanism anyway. So, as I said, maybe needless imaginings of horrible things that could go wrong, so I have hand washed my car the few times it has actually gotten dirty enough to bother me, which isn't often. But unlike joethebeekeeper, I find that my aerodynamic Clarity is a pain to wash and get clean. Its exterior has so many nooks, crannies, indentations, small ribs and channels that need detailing that, while washing, I find myself longing for the smooth, dolphin like exterior of a Tesla model 3.
