Introduction to Buffing

Buffing generally requires two operations, a cut buff and a finish buff. Even the cut buff, which is the coarsest buffing operation, is too fine for removal of pits, course abrasive polishing lines, or deep scratches. This is why surface preparation prior to buffing is critical to a high luster, final finish.
