I've noticed that Caswell greaseless wears out faster when you apply it with a fast buffing speed. It never really coats the surface well. You need a solid covering on your buffing wheel, and enough heat that it melts the greaseless and thoroughly covers the buffing wheel. You have to apply pressure with the compound to the wheel. What Maxi is referring to with pressure, i think, is pressure of the blade against the wheel with the greaseless applied.
