With good intentions I wanted my clear-glass headlights (Kunsstoff - Polo 6N) Clean and saw took the rough, dark side of a pot sponge. The result was a completely scratched headlights. Through good incorporation of the paste to the headlamp I have managed to remove 90% of the scratches and make it again "clear". For the price a real recommendation, before you think of a Ausstausch Pig thrower.
