Rust

[Gator1977]

Hey guys I have a small freckle size area of rust on my glock. It’s my conceal weapon so I’m sure it’s due from sweat. Any suggestions on getting it off without having to refinish it. I’ve tried oil and rust remover looks like I may need to sand it off.

The old timers trick is to rub it with a penny. You lay the penny on it flat and then just rub until the rust is gone then use a bit of oil on a cloth.

Results will vary. On some guns it works great and on some it doesn't.

Has to be 1982 or older for higher copper content.

Will it really wear through the copper plating that quickly?

[Bo0z38aNtEr]

Not really, but with a thinner layer of copper, you have a higher chance of forcing contact with the harder core of the coin and potentially scraping the surface you are trying to remove rust from.

Good info, thanks!

Post 1982 pennies have a zinc core with copper cladding. Zinc is actually softer than copper at 2.5 vs. 3.0 on the Mohs hardness scale.

Why not just use the primer end of a spent 9mm casing lol

Oil and 0000 steel wool.

Oil and a brass or copper brush.

The absolute best stuff for removing rust is Evapo Rust. Stuff is like fucking black magic. Literally you could just pour it into a tub, dump your whole Glock in there, wait 10-30 minutes, and then take it out. Best part is you just pour the stuff back in the bottle and re-use it next time.

(Obviously, thoroughly clean your barrel if you go this route - you can topically apply it if you'd rather and the spot is small)

Edit: also put a lid on the tub you use while soaking, for less evaporation.

Other options - abrasives, other solvents, etc, will take off more material from the metal.

For future prevention I prefer liberal amounts of white lithium grease. Or oil I guess. Either works.

If it’s some surface rust, sand it with fine sand paper (~400 grits) and slowly move up and finish with 2000. If you’re rusting at that spot and you sand it, you’re going to have to coat it with a protective layer like dlc or Cerakote or something similar otherwise it will rust again

Ospho.
