I remember reading something similar for the pins in an MG (or Triumph? not sure anymore) manual transmission. In this case the suggestion was to use peanut butter to hold the pins in.
One trick I discovered myself. When working on the car, your hands get very greasy dirty. It's impossible to wash it all off, it just has to wear off after a couple days. The trick is to rub your hands with Vaseline Lotion beforehand. Then the car dirt will wash right off.
Isn’t barrier cream for mechanics designed for that use?

#123Fun days for airport security :) How do they handle people bringing caramic knifes today? Would wooden knives display clearly on their scanners?
They barely deal with the people bringing metal guns. https://abcnews.go.com/US/exclusive-undercover-dhs-tests-fin...
Meanwhile, I've been quite literally screamed at by the TSA because I forgot to take the baggie with my toothpaste and deodorant out of my bag.

I don't know about that. But the Vaseline Intensive Care works great, and is cheap.

I was thinking "how would this do if fired from a nail gun" since as I understand it most commercial work is not done by hand nowadays anyways.

LIGNOLOC wooden nails are made from indigenous beech wood and boast a tensile strength similar to aluminium nails.
LIGNOLOC wooden nails are shot in pneumatically [using their specific nail-gun with reels of their nails].
LIGNOLOC wooden nails conserve tools and saw blades when post-processing wooden components in prefabricated buildings.
LIGNOLOC wooden nails do not cause any unattractive wood discolouration or leave any traces of corrosion, such as those left by steel nails.
LIGNOLOC wooden nails do not act as thermal bridges. This results in better insulation values and improved structural properties.

Probably dried jello, which can be sharp until it touches water.
A dried jello knife that turns into, literally, jello when stabbing someone... let's hope no-one beats me to Hollywood with that.

#128When I was a kid I used to launch Estes rockets. They came with mostly balsa wood fins that would frequently break on landing. The balsa wood also absorbed paint unless you hit it with a clear coat first. This for some reason gave me the idea of rubbing Elmer's glue on to it, letting it dry, then sanding it and then painting it. Not only did it paint easily but I never lost a single fin again. The closest I came to t…

Not to diminish your inventive skills but I'm pretty sure this was known back in the mid 80's when I was doing rockets as a kid. Googling it shows it to be a pretty common technique going back to at least the early 2000's.

They also created hardened wooden nails and hammered them into wooden planks. That seems like a better example.
Kind of. It took nearly two minutes to drive that skinny main though three skinny boards. A metal brad of the same size would go through that would in 3, maybe 4 whacks.
The way they were hitting it looked either like they had never hammered before, or that they were afraid of shattering the nail.
