What is buffing compound???? Its just a wax crayon with a powdered abrasive grit suspended in the wax. When you deposit the buffing compound on a surface you are also depositing the abrasive grit. Stroking your blades edge over the buffing compound polishes the cutting edge producing the finest burr you can produce.
If you want a hair splitting edge, cut apart an empty cereal box, cracker box, Minute rice box, etc. rub the buffing compound on the unprinted (grey) side of the box. Use your rolling guide with a backwards motion to buff the edge to a razor finish. Watch this video
