   Wow Kruza!
That's bizarre - I've never seen such rust before! And it was oiled before putting away?!

My SIG is just stored standing up in a locked cupboard - never any sign of rust.

What caused this do you think?

	Quite possibly the sweat from hands has reacted with the finish. I can be a bit of an acid old man lol. The finish is faulty. It's forming over the finish not through it. It starts where I break the barrel, but I noticed it on the metal rings around the barrel screws, had it this time. ( 3 days is the longest it's been unused) Its got me a bit stumped. If it was a moisture thing, I'd be expecting the 2 crosman to react as well, they all live in the same place. Which brings me back to a sweat reaction as the crosman are both pump up, no real barrel contact with hands. Not a issue had with tx200 in same case in same place. I'm open to suggestions at this stage. Probly have to do more research into the coating. I only have vague understanding of how it works from when I looked it up last time.

	Wow! That happened quick. Must be all the moisture in the air.

	Shouldn't do that on treated barrel. I was thinking the same, but the 1322 and 362 which start surface rust at drop of hat arnt doing it. I'm inland so not salt air. I didn't oil last night after I came back from mildly distracting hares from eating last night. ( a shocking night for just missed head shots, good night for hares) But it was oiled twice before I went out, so I'll be interested to see if it reacts. Wonder if the rem oil has reacted with the coating

	I had the same thing happen with one of my Sigs, forgot to clean it and oil it after a visit to the rabbits. Found mild rusting on the barrel 2 or 3 days later. Cleaned it and oiled it straight away. Ever since I have always oiled it after use and no further problems

	There's no sign of rust on it today. Though I have been guilty of getting back from a shoot and not oiling it, this was cleaned and oiled prior to it going away. Glad to know I'm not the only one who's had the issue. I'll probly just oil everyday for the next few days and see if it helps. Need to research the coating more.

	OK so the coating is a low temp harding technique . It adds durability to the metal and scratch resistance. The anti corrosion that you read about is a side effect of the process. Though seems to be a point of topic when discussing it with guns, it's actually not a point a lot of companies who do the coating emphasis to any degree. It's a minor point and does nothing but add a slight rust resistance. So I'm now thinking that I have been overestimating the amount of corrosive protection. The oil on barrel is just coming off thru cocking into my hunting Fingerless gloves. Thus stripping it of its oil protection. When it goes into the hard case the foam is absorbing light reapplied oil off from the barrel leaving it open to air exposure. All hypothetical but is the closest I've managed to form to a reason. Will find out over next week.

	Yep, I reckon the foam in cases takes the oil away.

	Interesting Kruza. I use a glove on my left hand to hold the stock when shooting and to cock the rifle. I only wipe over the rifle about once every 6 months with a light gun oil or INOX. I keep it vertical in my cupboard. And I've never seen a hint of rust, ever! If you try keeping your SIG vertical in a cupboard (like I do) - no cover, just open to the dry air inside a cupboard - then, if it still rusts, I'd say you have a coating problem that may be fixed under warranty? For cleaning inside the barrel I use Napier Power Oil but outside the rifle I use any ol'gun oil that I have handy. Never had any problems at all. Try the cupboard, vertical test for a week and see what happens....

	Well as it so happens work called, the peas started ( been driving most of night) which means 3 things 1: I'll be heading closer to town to a place with a gun safe, so I definitely will try them standing up in that. 2: my months of hunting when I please on an air gunners paradise is about to end for a while. 3: roll on weihrauch, 1322 upgrades, new scopes, big stash of ammo the guns like. It could just be case. (if the problem is oil coming off.) doesn't seem oily. Hopefully it is something I can fix by adjusting what I'm doing. Time will tell.
