A colleague of mine once used a jet wash at a supermarket to clean his new Mercedes and found he had grit blasted the paintwork to the extent it needed a respray. The cause was eventually determined to be an ill fitted/missing inlet filter on the jet wash, but only after a legal battle between the supermarket, the jet wash operating company and my friend. At one stage Mercedes became involved as the jet wash company said it must have been because of poor quality paintwork on the car.Be careful of the jet wash detergent/wash brushes, they are normally full of grit and brake dust and will scratch the hell out of your paint.
