Yeah, I use it with the same two bucket method and two sheepskin mitts. I do one panel before returning the mitt into the bucket, but I go through two or three panels before drying off. I do not find any dirt to be left on the paint. And there is no visible dirt on the towels IMO. Then with the remaining solution I wash my tires and wheels with another dedicated sheepskin. I have also seen no marring.
I now add some QD into the QEW mixture, thanks o scottwax's suggestions & it works great, adds a little bit of shine.
