buff on 5.5 (thats between the 5 and 6) to 6 on the dial, and work the XMT till hazes (flash cures). Consider three small lines running across the pad, and spritz pad with water or Qd'er as possible to dampen (very light) and extend polishing time slightly. All polishes will powder to a certain degree, but lots of it likely is caused by overuse of polish.
