I have had a flat or satin paint on some of my vehicles now for years. I could never find anything that cleaned and waxed the surface without leaving swirl marks from a rag. Within the last few years I tried a new one and couldn't believe the results. Made by a company with great overall products. My Napa stopped putting it on their shelves but will order it for you. Amazon carries it too. It's not cheap but the cost actually forced me to use a new way of applying it. I used to use a cotton soft rag or towel, but decided to apply it using a micro-fiber cloth and then hit it quick with a cotton after it dried. Cut consumption to 1/3. Just spray directly in the microfiber instead of the paint surface. What products have you been happy with??
