Not funny at all, but we can do this! First some questions:
Black granite - is it Black Absolute or Black Galaxy? There are some veins of these two stones that just don't like taking a high polish. We can still do it, but if the finish looks allright as far as the color goes, and it is a little hazy instead of highly polished then you will need to use Diaglo for dark granite along with a felt wheel and some water to obtain a high gloss.
Before I list the technique, what does the finish look like? Is it just a blurry or hazy finish, or is it a milky finish? If it is a milky finish (and by that I mean there is a milky white hue going through the polish), then you have not used the coarsest 2 grits in the polishing pads enough. That milky look is caused by polishing over some of the deep scratches instead of polishing them out. What you see is light refracted off the deep unpolished part of the scratch and then reflected/refracted through the shine (remember that all scratches in granite look white). If this is the case repolish the edge and use the coarsest pad until it puts its own "grain" into the stone. When the only scratches on the stone are the ones you made with the coarsest pad then move to the next pad and keep using it until its "grain" has replaced the "grain" of the first pad. Repeat through black buff pad.
If you do not have a milky hue call me tomorrow and I will go over this with you firsthand! To bring out the high luster with Diaglo you will need:
Your variable speed grinder, your backing pad, a felt wheel and some Diaglo polishing compound. Here are the links:

Turn the RPM down to position 1 or 2. Sprinkle some of the polishing powder over the areas you need to repolish. Mist over with water. Use the felt wheel to turn the powder/mist into a paste. Buff paste over the area (similar to buffing a car) until you have the desired result. Remember to keep the paste a little moist. You may have to do this process more than once to get the desired results. It depends on how high a polish your slab has and how much the stone was etched.
When you are finished with the polishing, wipe on the Hydrex sealer to impregnate the stone. This will stainproof it and prevent citric acid (and other acids) from etching it.
