I do not know how anyone can say this product works. The commercials show a man using the product on a black sports car, and it dries like new. I have a black Cobalt and used this product for the first time today, in the shade, and in 74 degree weather. I followed to instructions exactly and after rinsing I noticed the soap had left a white film all over my car! The water was drying spotless but the soap wasn't. The water also wasn't drying "before my eyes" either. I still had to end up going over my car with a cloth to remove the soap film. After I use all this I will not be buying a refill, if I even use it again. Luckily this was a gift or it would be going back to the store!
