After removing all defects and sanding marks with your favorite compound, set your rotary polisher to 600 - 1200 RPM's. Apply enough polish to work a 2' x 2' section to your pad. Polish with a slow back and forth overlapping motion. Make sure to keep your pad flat with the vehicle until all holograms and swirls marks are removed. You can also use ACA 520 with a dual action polisher on speed 3 or 4.
