mclean:
timmmay: I water blasted my new Nissan with the proper car wash attachment recently. It took a long time and the clean was poor. Next time I did a quick wash with a car washing brush, did a heaps better job. I think you just need contact to get it clean.
Agree, and careful with the blaster - cleaned the badges off my wife's BMW!
watch this weeks top Gear to see what a blaster can do
