OK, so here's my take on Z-8. I'm fairly underwhelmed. The car looks shiny as hell, but I did add 2 more coats of Z-2 pro, so that could account for it. I did 1/2 of the hood and stepped back, and I really couldn't tell the difference from the untreated side, though I was working in the shade, where it would have been hard to tell. From a distance the car looks amazing. There are a couple of spots where you can see streaks, but only if you're looking from a foot or less away. I used sparingly, and wiped completely dry. Also went back and hit the streaky spots, but they didn't go away. The anti-static properties are supposed to help keep dust off, but it's only been 2 days, and i have a good bit of dust. I don't see any real improvement. Maybe I need to use it a few more times, but as of now, my impression is that the Z-6 is as effective, and more forgiving to apply.
