The more you wash it, Polish it, Wax it, anything coming into contact with it such as with wipeing it down with anything is going to cause very small markings in the paint. Do not wipe in circles. wipe in horizonal movements lightly back and forth. Or ( Very time consuming) Blotting surface dry. Rubbing in circle will create circular marks in the paint and is very noticable in the sun. Back and forth movements will create straight lines in the paint and are very much less noticeable. Get your self a Car duster and use that going over the car very lightly to remove dust. The more you play around washing and such the more slight marks you will have.
