I also like the Nano which I tested against about 4 or 5 other brands I had around the house, which I did a writeup on and posted in the detail section, and it was the best at filling swirls and still seemed to do a good job along with removing some oxidation. To me it doesn't seem to stay on that long though as in the sun it seems swirls reappear after the next washing or so. Maybe a topcoat of some 3M carnuba might be something to try. I wonder if the new ICE stuff is any good...
