I have just looked out the window at my motor, watching the sun light reflect of all the curves, the thing is the car is covered in at least 1mm of sand all over, and from inside you can hardly see out! its not been cleaned for 6 weeks, my old red car looked dirty the next day after washing, but silver still looks mint form a few feet away after six weeks. I have had black and blue cars but this one looks better for far longer after a clean.
Hose and bucket out in the morning!
