So many people totally dismiss the one opportunity that creates the most amount of damage to their paint. That would be when you're touching it: washing and dust removal. Those are the two most effective opportunities for swirls and scratches to end up in you paint. So the question is, how are you washing the car? If you also remove dust from the car, how are you doing that? These two things along is when most of your paint damage will happen.

One thing to also remember. Washing your car properly while using crappy towels and mitts is the same thing as washing the car improperly.
