Brent,
You're probably going to have to go to buffing compounds at this point if you're looking to get back to that chrome shine that the older knives came with.
Otherwise, keep using finer & finer grit (up to 6000) wet/dry paper with windex as the lubricant. Then polish out with flitz or simichrome.
Just for safety I'd also knock the edge off until the polishing was done then re sharpen.
