Lapping compound is used in doing valve jobs to seat valves.
You you put a dab on the valve and with a plunger tool you stick the plunger to the valve and spin the tool with the palms of you hands.

Also for lapping prop shafts to properly mate a prop. (Yes, apparently its that hard to make a perfect morse taper)
