The Bon Ami deal was only something I heard about but did not remember how it was actually used. My apology for giving bad info there. 50 years ago is hard to remember. Makes more sense in the top of the engine and not in the oil. The stuff is abrasive and Pontiacs don't need any help with spinning bearings ....lol Total Seal sells a powder to use on your cylinder walls to help seat rings. I have used it. Maybe they heard about Bon Ami....!
