I was wondering which direction ( circular, front to back, side to side) is the best way to wax a car to avoid swirl marks that I see occassionally on detailed cars? I heard you shouldn't do circular motions because it will cause swirl marks like a buffer does. When I get my MZ3, it will be the first time I will wax a car ( maybe I will wax my Contour before I trade it in so it looks better to the dealer ). I don't want to make the car look worse than if I hadn't waxed it at all. All suggestions are appreciated!
