The ointment for my overnight dry eyes is half petroleum jelly half mineral oil. I can and have used Vaseline (which is almost entirely petroleum jelly) in a pinch.
I had an old Japanese truck, and when I replaced the oil pump you were supposed to pack the spaces around the gears of the new pump so it would pump oil. It was how you “primed” the oil pump.
Inject liberally into veins switches, connectors, and other electronic moving parts that I’d like to be waterproof. (0. Cover PCB in nail polish or specially-made products)
I used to use it with my hobo chiller of doom when extreme overclocking. I only use it to insulate the socket now, the board is covered in liquid electrical tape.
The hobo chiller of doom got upgraded to a water block glued to a peltier, and it’s still hobo as crap.
I have the same issue. Cocoa butter is my preference now, but Vaseline is quick and easy and available pretty much everywhere. Vaseline I feel helps protect my skin well, but cocoa butter actually absorbs into my skin better.
