Top Polishing Ab -black Granite (http://tanbrown.org)

I have been top polishing my Granite (http://tanbrown.org) seams for a while now. The only Stone (http://g603.net) that I will not top polish is Ab Black. This is because I have alway's heard it was taboo. I have a customer who wants this done. I have practiced on seaming and (http://maplered.com) polishing scrap, but am having a hard time getting the factory luster (polish). It still looks cloudy. Currently I am top polishing the same way as Mark's method and (http://maplered.com) having phenom sucess. I really want to top polish the Ab-black for this lady and (http://maplered.com) make it look great. Can anyone give me some tips on what has worked well for them, example - lots of water ect.

Any help would greatly be appreciated.
