(I guess I'll reply to my own message so it doesn't look lame)
I applied two coats this weekend and since it was my first time I was fairly surprised after reading everything people have written about it in this forum...
a few observations:
I used Z2 + ZFX and even though it sounds kinda odd to be "mixing chemicals" to wax your car, there really is nothing to this... just follow directions.
Once mixed, the Z works just like every wax I've ever used... although it is a bit harder to see where you've covered if you have Tit Silver.
Taking it off was a breeze... It isn't as thick and gummy as wax so I was able to wipe off quite a bit before flipping my towel.
Overall... I'd say I'm a convert. I've never really been *that* into detailing before I got this car so I was worried I'd hate doing all the work but it seemed in my mind not any more difficult than turtle wax... and with such great results (it was so easy, i even did the wheels). It makes me wish I had a black car to get more of a mirror effect, but I've never seen a silver car sparkle so much.
Anyway, maybe I should place my next order by the case.
