I washed my Passat today after the best part of a month. There was very little visible silver paint on it, but now it's all clean again...for now. One thing about this time of year is I don't bother drying it, so that saves time.
I could really do with cleaning the Mk2 as it is still dirty from get caught in the rain on the way back from MOT in October, but I'm not washing it unless I can take it for a spin down the road to blow dry it before it goes back in the garage.
