Wash your car not in the direct sunlight. Read the car polish label first because some products will stain the plastic trim and others have to be applied within certain temps. Work on one section at a time. Apply a one inch circle of polish to a dampened, clean, 100 percent cotton terry cloth towel. Rub the polish onto the car in a circular motion. Let it dry to a haze. Use a different towel of the same type to buff the polish. Then go to the next section.
