With regard to Joe Curry's recent remark about the decreasing
availability of Bon Ami, I submit this, which is a link to find retail
locations, state by state, for Bon Ami availability:
http://www.bonami.com/US_retail_locations.html
I don't advocate dumping this stuff into an engine, despite the folklore
surrounding that practice, but if one wishes to follow Kas' advice about
lapping in rings before engine assembly, the above link will probably
provide sources for finding this mild abrasive.
Cheers, all.
