The product does what it says. It missed my tires wonderful luster. It also keeps a while. , Even when driving times in the rain runs off the water. Only you should apply it in the evening when the car anyway then the night is so that dries something otherwise you have splashes can be seen on the body in my silver car. However, these are with a simple polishing cloth with short upward wipe away. On a dark vehicle seen not it. When I used it the first time has hardly lacking in bottle anything, so very economical. Because of syringes / long dry season and, for my taste, slightly overpriced price 4 stars. Will it, however, buy back when the bottle is empty.
