    No argument here, but even living in the deep south, I have never had an issue with long'ish storage of weapons in foam lined cases. What is most critical is storing in a cool/dry place....and letting a hot weapon cool before casing, a most-often skipped step. I've walked into my home with warm weapons (warmed by the sun), and immediately had a thin film of condensation build up on them.

I performed the same process as above, but made almost no progress removing it. Got my ass chewed when I showed it to my DS because the pin for the pistol grip and FCG had been lost a week before and our ghetto rig wasn't working (I had just ND'd because whatever solution the other DS had previously come up with had failed and the whole FCG and pistol grip slipped off the receiver. I think about 3 rounds went off before I slammed it back in place - luckily they were blanks). He didn't say shit about the fact that the FCG was being held in place by a twig and 550 cord, just that I needed to clean the rust off as soon as possible.
    Are you me? Our SAW's were orange by the end of our FTX, spent the first 4 days of recovery cleaning bravos and 249's 24 hours a day. CLP works fine you just need a bunch of scared and tired privates doing the work.

    I'll second the froglube and/or kroil.

    You may also want to try G96. So far (For me) it has worked excellent all around.

    If you have a spare bottle, send it to me and I'll fill it for you for free. I've got a gallon of the stuff.

    There is more to this story...

    The rust rate of 416 stainless is about 2 mils per year. The only way to rapidly increase the rate is to compromise the passive layer on the surface with blood, sweat, salt water or halogens (chemicals that end in 'ine'). Just about every "gun scrubber" on the market has something in it that is bad for your weapon. Is there any chance that the OP might have used a cleaning agent that contained a chemical that exacerbated the rust?

    What is Rustolum on top of Douglas Black Coat? If this barrel is rusting through the paint the OP likely has a problem that can't be fixed without refinishing the entire barrel.

    Does this barrel really have a chrome lined bore? I wasn't aware that you could apply hard chrome to a stainless barrel.

    I agree there has to be more to the story. Chrome lining should stand up more than this. The halogen family is group 17 on the periodic table.

    I know that Noveske did some 4 or 5 years ago, but I'm not aware of anyone currently doing it. It isn't cheap by a long shot, so I'm very interested in knowing who else is doing it, and why (aside from just being different).

    As has already been mentioned, you don't need to ditch the Pelican case, just get some closed cell foam for it and maybe some desiccant too just to be safe. Or, you know, sell it to me for half price

    Re: Help with major rust problem on my MK12.

    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.

    http://www.fluid-film.com/

    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.

    I had to store my long range rifle in a pelican case for quite an extended time due to a move, If you keep some desiccants in the case along with the gun it can make a world of difference.

    If you get the desiccants in the little altoid shaped containers they can be recharged and you can place a few of them in the case. It made all the difference in the world when I had to store mine.

    I bought my Pelican without foam and just put my padded soft case into it.
