Ideally, you would go from 1K to 2K to 4K to 8K. Since you are going from 1K directly to a 4K stone, it will take a lot of work on the 4K stone to remove all of the scratches from the 1K. If you stay at the 4K level long enough, none of the 1K scratches will remain. At that point, the 8K should remove the 4K scratches fairly quickly unless, as some have suggested, there is a problem with your Norton 8K.
