Bought this yesterday for my car. Dont know if anyone has used it before. I must admit I was quite skeptical as to it claims about how it transforms black paint. The paintwork on my car is not the best at all, it is full of scratches and swirls and it looks like is has never seen a coat of polish in its 6/7 year life. However I must say that the results are really good. When you get up really close or have a keen eye you can still see the a fair few of the swirl marks/scratches but from 2/3 feet away you cant see any of the damage and the paintwork actually has a shine to it. It is 1000% better than it was this time yesterday. Long term it really needs a paint restore on it but for £18 the turtle wax black box is very good as a start to get some protection on the bodywork.
