Bonami sealed the rings!

I heard of comet and bon ami for seating rings back in the 70's when I worked in my family's auto parts store. Dad was a factory rep for sealed power in the 60's and early 70's and would cringe when he heard of someone doing this. The only explanation we could come up with was that the cylinder walls were not properly honed during a rebuild. Having been "the kid" around the parts store, I got stuck with teardown of most of the motors that were rebuilt by us and employees. I've seen way more stuck rings than rings that were moving freely in the ring groves that were in "oil burners". Using the correct grit stones and correct cross hatch pattern when honing never caused us to have rings that wouldn't seat.
