That was the salvation for the beautiful unit (and my nerves). The case shines again. Rest Scratch are only seen in a good light in the backlight. However, just because I enough for me the result and I'm too lazy to continue polishing.
If you want, you can reach in only superficially scarred bodies a result, as if someone had just pulled off the protective film ... micro-scratches (as are formed by careless dusting for example) have disappeared after only a few seconds polishing. For coarser scratches you need more patience and each must hold a few minutes. The surrounding material has to be removed down to the level of the lowest point of damage. Therefore really deep scrapes with the Sonax polish alone are naturally difficult to remove - but they are at least significantly less conspicuous.
You can finish the polishing at any time, since the surface always remains smooth. Is best to use two clean microfiber towels - one for polishing of scratch and the other later for polishing and removing polish residues. Be careful near crevices that make you ill get the product out later, and of course with labels that are usually quickly polished off time with.
Full recommendation and of course full marks from me.
