The stuff Jon Brogden was referring to was a Silicone based paste Sunnen developed for the final hone on a Chevy Vega aluminum bore engine. Worked great on the flathead.
We used a tennis ball with a hole drilled thru it and a washer with a nut welded to it and two sheet metal screws run through the washer into the tennis ball on each end.
Used a long piece of 3/8"all thread in a drill and tightened nuts to compress ball for desired tension.
This was final step after honing on the AN-600 with two grades of stone, and then the crocus wrap.
