I have been taking my 2016 Outback only to car washes that wash the car by hand. This is based on reading, years ago, that automatic car washes produce small scratches across the car. I tried automatic car washes that are labelled as "touch free" when I search in Google maps, but when I tested them by driving our other much older car, they are not touch free. Is there such a thing as a true touch-free car wash? Or have car paints improved to the point that I should stop worrying and just use any automatic car wash?
