Works, but is also a lot of manual work

the set works very well, my headlights are clear again. They had become very milky.
The big advantage of this set is the price compared to the same set of Nigrin.
In addition, after must not be painted, there is a seal on it. This can be even without Lackierkenntnisse.

But:
It is entirely handmade, because you get quickly numb fingers.
Since I had to polish two main and two Spotlight, I have additionally purchased a set of wet sandpaper from 800 grit. So we went quite fast because the 800 has the gray haze cleared away quickly.
The set is just the beginning from 1500, which is much finer and would take longer.
Important is the basic rule when grinding: The coarsest papers (1500, with me the 800) makes the work so removes the unwanted milky layer. All other papers in finer grit serve only to remove the grinding marks of the previous.
In principle: the 800 has the milchie layer removed, the 1000s, the drag marks, the 800, the 1200, the stress marks of the 1000s, etc, then the polishing sanding marks the last and finest sandpaper. Main work should therefore be carried out with the coarsest sandpaper.
