Dry it with water (water sheeting) and then an ELECTRIC leaf blower. If u use a gas leaf blower, particles and fumes from the exhaust will attach to the clearcoat of your car. Check video #4 here:
Junkman's 2-Bucket Wash Technique - Detailing World If u are gonna use a towel, pat the car dry, don't drag it across the paint... but for 30 bucks I would get a leaf blower and use it only for the car
