Looking through my old BTM's I ran across a interesting comment by Bill Hall.
Not about Finesse-it, just polishes with abrasives in them in general.
He said:
"As you polish the ball, particles imbed themselves in the shell of the ball and these particles will later redeposit themselves on the lane."
