ISTA says "anti-friction agent." thanks, that's useful. internets say use vaseline. wait, no, don't. use silicone, but as long as there's no silicone in it. use engine oil. but not oil.

dafuq?

i have silicone spray, engine oil, assembly lube, vaseline somewhere (good thing i still have a toddler i guess?)

do i need to pause and go buy some PTFE grease? or can i just use clean engine oil?
