Help with major rust problem on my MK12.
I opened my Pelican case to a very rusted MK12 Mod 0 tonight while getting something off of it. The barrel, which has a rustolum coating on top of the Douglas black coat had rust on it that I can clearly see through the holes of the PRI handguard. The chamber has rust in it, and the inside of the barrel was coated. In my hast to get the uppper stripped to start treating the rust, I have two allen screws that cannot unscrew. i did not locktight these either. They consist of the one allen on the added straight top forearm rail, and the allen screw that holds the Ops Inc suppressor collar in place.
I'm not worried so much on getting these last two screws off as this will be going to the smith tomorrow afternoon to handle (home built). I am very frustrated and curious as to how I got so much rust on this weapon in the three weeks since I cased it after a quick barrel swab and some CLP put on it.
My last outing with it was with my neighbor shooting at some pest deer destroying a friend's garden here in TN. We did this shortly after a rain soaking but the rifle was not uncased prior to that.
I have everything I thought has been right: keep it cased in a quality case, keep it lubed, and generally cleaned. I am mad beyond reason right now. What did I do wrong? Can my barrel be saved?

You folks have probably never heard if this stuff...
BUT IT WORKS....it is lanolin based, safe for wood, plastic, rubber, paint, any metal....anything. Excellent lubrication and protection...not so much for cleaning though.
It doesn't dry out either...I've even used for fifth wheel lube on a tractor trailer...it lasts longer than grease.
It's called "Fluid Film".... Google it or look it up on YouTube...I've used it on my guns for 2 years now, nothing else compares.

Can be found at most any Case or New Holland construction or agriculture equipment dealer.
Caterpillar, Case, New Holland, John Deere, etc....they all spray equipment that gets shipped overseas with this stuff...even when shipped top deck and uncovered....they arrive rust free after weeks at sea.
Some say it will begin to get gummy.....at about -10 F...I have not seen this though, I also use it on ratchet binders and it appeared to work just fine at -43 in North Dakota last winter...I haven't had my guns out in weather that cold, I prefer to not get myself out in it either...but sometimes I have to.
My guns are always stored ready for long term...after deer season, I leave home sometime in the first week of January and most likely won't be back until the middle of May.
