This is a heckuva story although most of it occurs after 1939. Click on the link to learn more.
“Chestien Wynn, a 70 year old retired attorney with an interest in lubrication chemistry, discovered a formula he named ‘Wynn’s Friction Proofing’ Oil. This surface treatment for metal actually changed the chemistry of the metal, making it softer and better able to withstand friction and wear.
“Chestien Wynn would mix a batch of his product in his one car garage workshop, fill and label glass bottles with it and sell them to the local service stations and garages. Motorists, who used the products once, wanted another bottle of it.”

When I initially commented I clicked the “Notify me when new comments are added” checkbox and now each time a comment is added I get several emails with the same comment. Is there any way you can remove me from that service? Cheers!
