I was curiuos about this product so I bought some and had a chance to try it out today. It smells great and the packaging is top notch. Application is easy, I prefer to use wax as you dry products on a freshly dried surface, and it glided on over the paint smoothly and left it very slick.
It does indeed have filling properties. My DD is black and only got a quick detail in the spring so it has the usual small marring here and there, nothing you could see unless you were inspecting the paint. After two hours I took a look and found the paint to be near flawless! I am impressed!
The price is nearly double AW, and I have yet to see the durability (or even the 24 hour slickness) so I will hold out my judgement on whether to buy again. But so far, on a black DD it seems to be the ticket. I think glaze + fk1000 + Hydro will be my go to this summer.
