I'm a big fan of it. Its not as good as 3 coats of UPP by itself, but it works. I've tried the whole layering different sealants and carnauba thing. I've come to realize that it doesn't get much better than 3xUPP and an S100 topper (strictly for the rinse effect). Through all the layers of SG or UPP or combinations of both that I have done, 3xUPP has pleased me the most on my white car. It may be different on other colors.
