That makes a lot of sense. The paint on the truck while smooth because I recently clayed it, was no longer slick after the automated car wash. It stripped my synthetic wax. Now I understand why when I washed the truck yesterday it did not beed up anymore. Thank you as you answered my question. Now I know why one should not use a touch less automated wash. Thanks for explaining it. Now I know I need to wax my truck again.
