The scratches that do not go through to the primer, disappear almost completely after 4-5 times will hand-polishing. The deeper "colleagues" that can already detect the coat, are slightly darker and take at the edge regions also somewhat. But you do not go away completely. Here, then, no wonder can be expected. Enclosed was a small black repair pen, which looks like a small crayon. This is for very deep scratches, in my opinion, but at most only for gross plastic elements (bumpers) suitable and gelatinized in principle for some time, the defect sites ....
Basically, this polish is for pure black lacquers, also metallic to good use. According to specification can also be different lacquered black plastic material treated with it.
It is a neat polish and ok for minor scratches, I would forgive nearly 4 stars for price / performance.
