Help with rust

[pogo]

........ I always thought Stainless was supposed to be more resistant to rust than this. ......

I don't know this model well, this is a stainless slide then?

Quality grades of stainless won't rust, but surface remnants of carbon steel tooling used to work the stainless piece that aren't removed will eventually show this kind of oxidation.

It sounds like SIG didn't do a full cleanup of the piece before it left their shop.

We installed/welded stainless frameworks on the seawall of a few Malibu beachfront homes, and never had a rust problem beyond the above described residue of carbon steel tooling. Once buffed out, the rust wouldn't return.

It's odd, but if we come back to the beach installation years later the stainless, hit by salt water every day wouldn't be rusting, rather it would just 'disappear' in little spots here and there.

Light surface rust can usually be removed from blued gun parts by soaking the surface in a good gun oil (like BreakFree) and then using the edge of a pre 1980 copper penny to scape the surface rust off usually with no damage to the metal or finish. Once the rust is into the metal (pits) you probably will have to refinish or hard chrome the parts. In my experence, the product called "Rust Prevent" by I believe, Burchwood Casey will keep most guns rust free. Good luck.

Auto body supply places sell a product called "rust mort" which works very well and leaves a zinc phosphate coating on the (formerly) rusty areas, although I would try the fine steel wool and light oil (like 3-in-1) method first.

Don't rust-mort your gun! If you're working on a $20 shotgun than yes, go for it, but this a quality pistol. I've used that stuff many times, and this is not a place for that.

Foam is for trasportation. Do not store metal on or inside foam. Another vote to get rid of the foam. I'm surprised they use foam inside the gunvault and not something else.
