IMHO, its easily the most underrated wax available. Beads like crazy, very good depth and wetness with great durability. It was a steal at $50. As P1et said, get it on thin. If you cant see your reflection, it's too thick. Drying times vary, but it likes to dry before removing unlike most waxes. The swipe test is your friend. Also, the polymers make it metallic friendly.
...Depending on wash products, 4-6 months. Here are some pics from my Passat.
