I 'm surprised no one else does this. I have a dedicated leaf blower to blow dry the car. It blows off most of the water, but best of all, I can blast off all the water that can't be seen, like in the crevices of the window sills, the grill, body seams, mirror cavities, around the hood and trunk. You know, the water that shows up as soon as you move the dang car and leaves spots all over when it dries.
Of course, you got to be careful with an electric one. I usually move the car to a dry spot before doing this. Of course, your neighbors don't get to excited about this at 6:00 in the morning... so be reasonable. P.S. wear a ear muff, so you don't go deaf.
