Rust protect gun?
 

Suppose you were going to carry a blued steel gun in a way that assured it would get wet from rain and sweat. Just assume there is no way to avoid it. Is there something you would apply to the gun to reduce rusting? WD40? It isn't a valuable or vintage gun so you're not wigging out about it, but you'd like to protect the gun to the extent possible.

A good gun oil and a good wipe down at the end of the day should be sufficient. Whatever you do, do not use WD-40.

What Neil said.

I carried a S&W model 28 for years. A daily wipe down with Rem Oil worked well. Any holster wear that I encountered or any surface rust that I experienced from the elements, I would buff with a piece of kitchen scotch brite pad and then treat with a good quality cold blue and then re-oil it.

I'll add this as well, for some reason the blueing on air guns seems to be less robust than normal spoons. I have had to retouch them from just sitting in the safe. I have used a product called Corrosion X and it seems to have been working pretty good.

Have you tried ACF-50 ?

I use the Corrosion X as well.

The leather holster is also going to get wet. Treat with silicone or something else? I'm thinking of it trapping moisture against the metal.

Not off the top of my head, I do have some stuff that I bought at a gun show that is really good, but the thing about it is, is that it stinks really bad. I mean like bloated road kill on side of the road in the middle of summer. Can't get to it now without waking the boss up, if I remember, I will get it out tomorrow and post what it is. On another note, at one time I had an old metal can of military issue stuff. It was probably either 1960's or 1970's surplus. Can't remember what ever happened to that can of lube, it was a dark brown honey / oil color, and that was some high grade stuff. I think I bought it at Academy way back in the early 90's for about .99 cents for 16 ounces. At the time they had one of those metal cages (that wally world etc.. keeps those cheap rubber inflated bouncing balls in) that cage was full of U.S. Army steel pots (helmets) and British Doughboy helmets for like $2-$5 dollars a piece. If I knew what those things would be selling for today, I would have purchased all of them.

Never use a leather holster if you know it's going to get wet. Get a cheap nylon Uncle Mike's or something.

Break Free CLP does a good job of protecting blued guns from rust.

Or duracoat or just have the gun parked and then paint over that. Has worked for militaries for over 100 years.

Anyone use Boeshield T-9?
I use it now and then...wipe it off well.

Here's where I show my ignorance.
I thought the color of Parkerized weapons used by the military came from their storage in cosmoline which changed the grey to light olive.

Depends on the military in question. But a lot of the stuff that has seen years of use and abuse (S. American FALs, FALs from various parts of Africa, the former German and then Turkish G1 FALs, etc) were parked and then painted.

The parkerizing can give different color depending on the actual chemical mix used, the metal being treated, etc. You'll also get color changes on heat treated areas. A nice coat of paint over all of it makes it all the same looking.

All the oil choices above (-the wd-40) are good.
I'll only add Rig rag to the list. Very handy for daily wipe-down, which is probably the most important thing here.

Take the gun out of the holster when not worn.

I also use Boeshield T-9. I use it on lots & lots of different things for lubrication & a bit of corrosion protection.
