I`m considering buying a foam gun that attaches to a garden hose and have a few questions. I wash in my garage, does it spray all over the place or is it pretty direct? Secondly, how do people use, do you spray the whole car down and then wash it off, or do you leave the foam on and then use a mitt to wash the car down? If you spray the whole car down, can you do the car fast enough so the foam doesn`t dry and cause spotting?
Thanks in advance.
