I work blind spots and rust spots on Mopped- parts with it and think it could be better. If I compare it with the good old "Elsterglanz", the result is just too puny. However, it could be that here the Putzkörperchen are finer, and thus less aggressive anschmirgeln the chromium layer and you have to polish only with more patience or by machine. Whether a layer of protection against new rust arises, as claimed on the bottle, I can neither confirm nor deny.
