Consider when you wash your car that you are the one who is inflicting swirls on your paint(which you have to polish out later), and wash with this in mind. 2 or 3 bucket wash, foam gun, dual wash pads, all are your friends that help keep you off the polisher.
My neighbors think I'm excessive the way I wash and dry my car, but they always complement me on how it looks. And I don't polish it every 3 months either.
