Guido, Lapping compound is an abrasive that is suspended in some sort of medium,
some water based and some oil based. It usually comes in different grit sizes
such as "fine", "medium", and "coarse". Old mechanics used this stuff to seat
valves on cylinder heads. Has many uses but mainly to remove metal as sandpaper
does.

I used a water based valve lapping compound on my left
aileron bearing this evening and the results were
excellent. After working the compound into the
bearing, I worked the bearing back and forth for about
10 minutes and then flushed with running water. I used
penetrating oil to capture the remaining grit and
flushed with spray carb cleaner until it ran clean. I
reinstalled the left flap and aileron and now there is
no binding.

Guido; Lapping compound is slang for valve grinding compound which gained
the name from doing final (lapping) seating of valves and seats manually.
The product we use is Permatex Valve Grinding Compound (water Mixed)
manufactured by Loctite Corp. Farmerjohn

Here is another use:
If you have a phillips head screw that you can't loosen because the tip of
the screwdriver keeps slipping, just put a dab of Lapping Compound on the tip of
the screwdriver, and Presto !! Keeps the screwdriver from slipping. It
works.
