a few tips:
1) use WD 40 or Tap Magic for lube, not water. Water will turn the parts black and ugly
2) after using paper, go to red scotch brite, then grey finne scotchbrite...use same oil her too
3) when you use a buffing wheel, use green wax first, then white wax to finish up....
4) for extra bright shine, some hand polishing with Flitz can help too..
