I drive a car Obsidian Black, that in winter you can see any dirt, just as in the summer all the dust. I have tried several other paint protection products. I am very satisfied with this product. The cream can be really apply very easily using the enclosed sponge and wipe gently with a microfiber cloth. It's really like a abblockendes shield. Salt hardly adheres and is washed away by the next rain. The water runs really very well. If you drive in the rain to get to almost dry :-). Even if it freezes, the ice can not really adhere to the disk and can also scrape away much easier. Over time, however, obtained matte ruts from running water (eg moldings, the mirror down). In the summer, so if only dust is on the car, the agent is best, simply hose down and everything is clean. I have maintained my car twice so. Once in the summer and then before the beginning of winter. The protection will, as promised, reactivated after each wash. He thinks even now still, although I go a lot on highway and city and have already had a lot of salt on the car. My black paint gleams then again wonderful, and you can reflect it back :-) I would recommend this product only !!!
