It's one thing to remove the old dry film lubricant. It's another to remove the anodizing. From what I've been told, bead blasting removes the anodizing, which supposedly is not really a good thing.

I have an old 20 rounder whose finish was very worn out. I took a fine grit sandpaper and decided to remove all of its original finish. It actually looked good in the raw.

Since aluminum does not rust, I assume that the main reason for the finish is make it non-reflective.

IMO

Oh BTW, I did that several months ago and the mag is still ok.

Isn't bead blasting for polishing? It might be quite tricky to apply new finish (assuming you would ever want to) in the future. MJD

aluminum does rust, a good kind. It has two names aluminum oxide and anodized aluminum.

Exposed aluminum can oxidize. There's a reason you don't see exposed aluminium on mags and weapons.

Spray some Hoppes on your shiny mags and see what happens

I probably wouldn't use a highly abrasive media like sand or glass, but something less abrasive like walnut may be suitable if you just want to remove any finish that was previously applied over the anodizing.

Aluminum does corrode... you don't want to remove the anodizing.



But I am positively convinced the reason for the gray dry lube finish is to make it non-reflective. This is not a part that requires "lubrication".

Hard anodizing resists corrosion and wear. http://www.designinsite.dk/htmsider/p1135.htm
Adding a dye to the process can give any hue you wish. If needed paints or dry film lubricants will adhere much better. You can do this at home.

Be carefull how much pressure you use as you can warp the metal .
