It seems using a foam gun that covers the car in foam is becoming popular as part the detailing process. Seems covering the car in a cleansing foam that loosens dirt while (allegedly) lubricating the paint would be an effective method for cleaning the car.
But before I commit to spending the money, I'd like to hear from folks who have used it. Is it yet another gimmick to get us to spend our money? Or does it actually make the detailing process a bit easier and more effective?
