Badgerarms,
"Blasting these removes the alodine which protects the aluminum. Painting them with anything but DFL makes the magazines more sticky than they were designed to be. Neither action is advisable."
Yes, the alodine is placed there as an inhibitor to outside influences attacking the aluminum in the mag. However, a good automotive primer will do just as good. How many cars fall apart from bad primer paint jobs??? Not many. And the exterior paint I used has been less susceptible to scratching than the paint that the military uses. And, if properly cured (dried), will not impede the insertion or removal of said mag from the firearm. Remember, I have ten of these suckers and NONE of them have the problems you describe.
Lets talk about brownells teflon paint. It's really not worth the money you pay for it. I have used it on many occaisions, and in every instance, it doesn't work nearly as well as regular automotive paint. Why? Because that can of teflon paint is not the same as the $10,000 a gallon Dupont teflon paint as used by the military. If you want to coat your magazines with that type of teflon paint, send them in to Rocky Mountain Arms. RMA is the only company that I am aware of that DOES use Dupont teflon paint, as designed for the military. Even their paint can be scratched off if you are not careful.
It's apples and oranges. None of us has the monetary depth of the US military and substituting 'lower grade' products, just because they sound like similar, doesn't mean they will perform the same. They won't.
I use products that I KNOW work, because I have tried them in the field. The only advice I put forth here is from my own personal experience.
