guys, I was in the car wash equipment industry..... touchless uses more aggressive chemicals.... over time, overly done, tough on your clearcoat, polycarbonate headlight lenses and lesser plastic trim pieces. The right "friction eqipment" does a respectable job and is endorsed by the majors and the german luxury majors. It uses sope, water and friction, like washing your hands, or a hand wash of your car.
So, do what you want, but don't be lulled into thinking touch free is good for ur baby.
