I enjoy using it as well. Before I got the rotary I had some etched in
water spots that were only noticeable on my metallic grey Lexus from certain angles. My regimen was to put on the 3m imperial hand glaze in the etched areas and Megs #16 paste wax on top. I actually got pretty good durability from it, and was happy with the results look wise. If you have a car that has swirls or water spots and don't want to do a full correction, I think it is a great product for filling! Remember, the thinner the better!
