It will attack all edges much more quickly than flat surfaces, much like a sander will when you run it across an edge. How much material gets removed is a function of time and the agressiveness of the particular media, and has to be determined via trial and eror for a particular part. Left long enough, the part will disappear. The learning curve on polishing isnt too steep, but you just have to do it to learn what works and what doesn't. |
