I am "someone who works with metal." I'm a knifemaker, engraver, gunsmith, jeweler.
Metals do not absorb oil. Oil will stick to a rough metal surface better than a smooth one, but it is no absorbed.

I used Essox synthetic lube, on many of my firearms. I can't find it now. It gets more fluid when it gets warm from shooting etc. Rig +P and other ,lubes. Several of my firearms are parkerized. Nickel looks nice, but don't use Hoppes and some others solvents on it. there are many types of durable finishes out now....durable to a point. They will still scratch and rust and be worn off by holsters and other things. Only real way is for the base material to be rust resistant or rust proof, like some grades, of stainless. that is why most of the handguns, over the last, 20 years, I've acquired were stainless. when they come up with something that won't rub off on the edges and corners and normal wear, they will beat a path to their door.
Drenching hot metal in oil is a form of hardening the metal. If you dip hot metal in water it gets to hard and becomes brittle (the fate of the titanic). Hot metal burns the oil. Burnt oil forms carbon which does nothing to prevent rust or corrosion but it does form high carbon steel which makes a decent knife.

Both of you guys are way out of your leagues.
Burned oil has nothing to do with making high carbon steel.
Please stop!

Actually, many metals are porous, and will "absorb" oil. The same as they

will absorb moisture, if given the chance.

I just got a stainless steel rifle some jackpipe sold, because he

learned the hard way that SS does not mean rust-proof.

You still have to give your firearm some TLC, now and then. I have

also seen some of the toughest SS surfaces on the planet, Victorinox and

Wenger stainless steel penknives, rust through due to neglect and

harsh treatment.

Maybe they will find some rust proof treatment some day, but for now,

there still is no substitute for proper lubrication and storage of your

firearms.

Again, what happens on the surface of steel has nothing to do with the metal "absorbing" anything.
By their very nature, metals aren't porous. Surface texture is something completely different than metal composition. A rough surface texture will hold oil (or water) better than a polished texture, but that has nothing to do with the metal absorbing anything.
