I disagree with his reasoning for not using a lubricant.
Oil will float the rust particles away and help insure the rust doesn't continue scratching the good metal after its removed from the gun. It will also prevent surface rust from forming while you work on the rest of the gun.
I have a solution Buy a new one good for the Soul!!!!!!!!!!!!!!!!!!!!
And if anyone should be scuba diving and find stuff from boating Accidents we now know how to make them work again.
The first thing I would do is coat everything in a penetrating oil like Kroil. Start cleaning with the least abrasive method first (soft cloth) and work you way up from there as needed. I would keep it coated with oil the whole time.
That's so silly. You can't "rust" anything that is anodized. If your aluminum frame is rusting, than it's not aluminum. And titanium (different type of anodising process) also doesn't rust either with or without the thicker oxide layer, so that article I didn't even bother reading. Nitride, oxide, blueing, and sprayed surfaces etc is what's done on steel, you don't anodize steel.
About the only thing that I agree with in that article is the use of copper and brass wool and cleaning brushes. As far as the suggestion of not using any oil at all. WTH is up with that!!??
