I have bought and used this Wax with the speed shampoo. Applied to my 1year old black car and am very happy with the result. I have it applied in early October at about 15 degrees in partial shade, applied to the sponge and dry polished a microfiber polishing cloth for TV. Because the car is still so young and still has no scratches more I could not pay particular attention to whether it scratches also sealed but the result was no shadow, Schlieren, holograms or residue on plastic just super. Even now, 3months later, pearls rain still from nice. Clearly there is salt and dirty streets still dirty, who here offers a lotus effect is wrong. But briefly speed cleaned and shines it and runs off again. Super stuff and productive it is auch.Reicht safe for 3 or more applications.
