Just a tip, if you use a stiffish detailing brush or even a paint brush with the bristles cut down a little it will het in all the tight bits a lot better, you could also spray the muc off on the van as you did but then also spray in to the brush. When washing it down you could use a garden spray bottle that you pump up, or even get the bigger size that has a small hose with a jet on it. Roof looks so much better good job
