Rainman,
The best way to remove hairline scratches/swirls on a black piano finish is with some 3M products basically made for the auto industry. I would start with the Imperial Microfinishing Compound and finish with the Foam Polishing Pad Glaze. You can apply these by hand using a very soft cotton cloth and some muscle or get a orbital polishing machine. Be sure to use a different cloth or pad for each product and work fast. If you still have scratches after that you may want to step down to the Super Duty Rubbing Compound and then work your way back up the the Polishing Glaze. Any supplier to the auto or wood finishing industry will carry these products. A coat of Rain Dance car wax after the polishing will help retard further scratching, but nothing will prevent it unless one never dusts/cleans the surface.
Best,
Merganser
