air dry after washing it. What I mean by this is....wash your car with soap and water, rinse it off, and let it air dry with normal hose water. I would NEVER do this to my cars, but I know several people who do this and are too lazy to dry it down. Before I came along, my g/f did her car like this and she would often spray it down with water to get mud and dirt from her dirt road off the car....then let it air dry. Ive taught her better now after a good Autopian detail, but her parents are doing this to their new 03 Malubu they picked up....reguardless to how much I say its not good for the car.
