about the megs drying towel. Nothing is illegal, haha. Its all down to yourself how you want to care for your car. One thing i will say about the megs water magnet; aftep a few months of use, they can start to become a bit scratchy. Well, certainly in my experience. Best yay to check its not like this is to find a cd, and rub it with it. If it leaves behind any scratches, it will be doin the same to your paint.
