What is this? The mags were recently bought (refinished, of course). Place is out of business. It is crusty/flakey white stuff that brushes off and comes back over time. What is it and how do I stop it?

 

FYI: This is NJ legal. It wont feed ammunition. Its for a blank firing gun. Mag is a thompson mag sleeved backwards for 9.3mm blanks.

From what I can hardly see, it looks like galvanic corrosion. Are there dis-similar metals there? Is the follower steel and the mag aluminum?

 

Before you ask - http://en.wikipedia.org/wiki/Galvanic_corrosion

You're not storing the magazines in a salt water bath, are you?

Not dis-similar metals. And its coming out everywhere that it can from between the 2 bodys. And no on the saltwater haha. Someone mentioned something about battery acid on another forum. Is that something like that in blueing? Sure looks like the crud from car battery terminals now that I think of it.

are the sleeves in the mags a cast aluminum or pot medal

Looks like oxidation. Wherever you're storing that mag it's causing a reaction with the stuff on it. You can try putting a desiccant in the case along with the mags.

Put em in a Baking Soda bath..... that should neutralize any reaction that is happening.... then store em someplace else...

My quess is if these were blued,the blueing in the parts not nuetralized after blueing. The ussual process is to blue in salts, kill the effect of the salts in hot water(skimming residual salts off the top) then place in water diplacing oil. I don't think the salts were ever nuetralized if these are blued parts.

 

As long as there is no plastic, boil some water, throw them in, let them soak for a while, air dry then, oil them well. Oh cleanthe stuff up before you do anything
