I still agree with T_Kiwi,
although there is an obvious difference between polishing edge profiles or horizontal flat surfaces like draining boards, were it is possible to achieve a near acceptable polishing, at least on softer light colored granites but not so much on darker and harder granites. I also had good results on engineered stones with polishing draining boards but it took a lot of fiddling with the program settings to get near random movements for all tools and still cover all areas equally.
