Apply very light pressure to the paint when washing/drying. ALWAYS move in a forward to back motion when washing/drying as well. Think of it like this ....... you're moving with the grain of the paint (the direction in which the paint was applied) thus the paint is less susceptible to the dreaded swirls. Swirls are generally caused by washing/drying/waxing/wax removal in a circular motion.
You'll be pleasantly surprised with the results if you practice this technique.
