Looking through an old bin at the back of a long disused workbench in the store room and found this can of penetrating oil: The parts man whom has been there well over 50 years says it was a very good product. Although the pressurization is gone in the can, the lubricant is not. It was compared to modern day "Kroil" or something like that. Much better than "P'Blaster" I'm told.
