no unfortunately not yet. i'll be using it on my car this weekend. it's supposed to protect your paint from the elements for 7 years, and is actually guaranteed. i got a certificate today to use it and be under that warranty because they came in and did a demo.
it's not a wax, so it's not noticable. it's like a protective film you wheel and do whatever to the paint to get it how you want, use some finishing material or cleaner wax to get hazing out, apply this stuff and you put wax over it. it's a liquid you put it on and wipe off right away. we used it on a small section of a black cadillac xlr, it was so smooth you could drop a piece of paper on it and it'd just slide off.
an application from a certified dealer or detailing shop costs around 1000 dollars. the bottle costs about 300. this was a demo bottle so it was free.
