Hi, im new to this but have a cracking idea to put the Romanians out of business at the local supermarket. I need to buy a van with a big barel in the back and one of those whose reels that are very long. I could get a water Fred pole with a brush and just walk round the car park all day and squitr the car an rub with brush and charge 3 pound a car. Do you think this would work. Or not. I think I could clean 10 cars a day easy.
