Na mate I read some where that if the vehicle is not wiped and if it is done often it can damage the paint work and all (Didn't explain properly - it said about minerals settling on the paint work and staining) This didn't make much sense to me because, I was thinking hang on what happens when you go in the rain and all. You would never wipe your car rite. Also if the car is waxed then water should run off without any retention rite. So if there is the risk of swirls being put on the paint work if not wiped properly, is it not better off to let the vehicle dry over time, was my question.
