Here's mine. It's about half full. It has to be ~40 years old (1980-ish). I grabbed it out of my father's repair shop and never returned it. I have to stir the contents when ever I use it (rarely). The brown snot is Permatex No. 1.
When I was in community collenge, I used to work summers at Hewlett-Packard in the model shop. What a bunch of comedians. Someone put a dab of Prussian Blue on the quill handle of a Bridgeport. After a few minutes the victim looked like a member of The Blue Man Crew.We used a product called Penetrox on high voltage connections . It kind of reminded me of anti-seize . One little blob the size of a nickel would end up covering your hands , your shirt , etc..
