I have used it, both liquid and paste. Of the two, I prefer the paste as it is easier to spread, but once you get past that, it does take a good long while to dry. If you don't wait long enough for it to dry, it will tear your arm off if you try to remove it, much like Collnite or Meguiar's #16. This should also be a hint to do SUPER thin coats. Water beading and sheeting is second to none that I have seen so far, though I found Meguiar's NXT 2.0 to sheet just as well, and protects the paint fairly well. It does not give the same look as NXT 2.0, but it is good stuff. The spray stuff is also pretty good, and does what it promises. Nanowax also does not stain trim or leave white residue, which I liked A LOT.
I will say though, that the NXT 2.0 and UQD is a MUCH MUCH easier to use combo so long as you stay clear of the trim with the wax. UQD also works as a detailer and a boost of protection to NXT which you would have to spend extra time with Nanowax spray only after you used Wipe and Shine.
So yes, it is good stuff, but I personally would just recommend the Meguair's stuff.
