It’s great for keeping rust off tools. Just the slightest whiff of vaseline will keep rust away for years. I tend to use a spray can of vaseline for that though, not a tub.
I use it as anti-seize for RF connectors. It allows cables to connect to antennas without getting stuck, even if left like that for years in maritime environments.
EDIT: Just make sure the vasseline is neutral and not (even slightly) acidic. Otherwise it’ll cause corrosion.
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.
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 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.
