What I am saying is, using anything on a vehicle before dust or other contaminants are removed, is going to cause scratches, and swirl marks on the finish.

Not removing dust and dirt particles prior to rubbing the finish with whatever product, is going to create unwanted marks on the finish.
I would never even take a soft micro fiber towel to the finish, until I remove surface crap first by hosing it down.
