It can be done i didnt mean that it was impossible. lol. He probly doesnt have time to wash it himself and its like below freezing or close to it so that makes it really rough. I do wash my car when its 34 degrees just cause i think car washes at the drive through thinger are totally pointless. You go through, come out, and people can still draw naughty things on your car in the dirt that it doesnt get off.
