the granite was originally polished using varying grits and a power buffer. You could try using various grits of "lapping" compound on a small section to see how it takes to resurfacing. Then I'd tackle the larger area using the same lapping compound and a low rpm buffer. if the scratches aren't too deep it should be possible to buff them out using the lapping compound. lapping compound is different grits of carborundum in an oil vehicle - carborundum is silica carbide
