The perfect result, it is not, who wants to have an absolute flat surface should still work over with a finishing polish.
To erziehlen a very good result after the rough polishing or after wet sanding (a few scratches in direct sunlight) is to recommend this product properly. If that is not sufficient, which should as has been said, then apply an even finer polish.
For processing:
was processed by hand with polishing wool in the first round, after that 2 passages with Microfastertüchern.
Very easy removal with microfiber towels.
