Chase,
did you do this across the entire top surface or just parts of it? If it is the entire surface you should take the slab to a shop that has a radial arm polisher and let them do it for you. If it is just certain parts use a set of pads designed for top polishing like these:

The lighter finish usually means you did not use the coarser pads enough. If you need to discuss this with people who can help our office number is 800-289-6834.
Glad to be of service,
Mark
