I actually posted this for the comments, besides that the product looks really good and application method is unorthodox. I am used to applying coatings dry (I am still using normal wax), this one wet and hose it off and seems pretty quick to coat whole the car probably around 10 minutes. Watch the video on the product web page.
Unfortunately the Happy Endings is not on sale.
