Have this polish bought due to the positive feedback, but this may even not confirm. From because of "too deep scratches are polished away"! I have done everything as given, left me a lot of time, and so on ... The result is rather poor, even not quite as bad scratches are still visible. In addition, the already tiny tube is only half full and therefore far too expensive! Well, it was an attempt - now I have bought me a new smartphone and the screen provided with a protective foil. I can change if it is scratched, there brauchts not paste!
