0 - Salt, Vinegar, Battery Charger, Stencil, Glass Cleaner

1 - Unetched Magazine Cleaned With
     Glass Cleaner

2 - Self-Adhesive Numeral Stencil Positioned
     The key is to firmly press the stencil in
     place so the edges are sealed.

3 - Stencil Taped In Place

4 - Positive Lead Clamped To Prepped Magazine

5 - Etching: Q-Tip Soaked In Vinegar/Salt Solution
     Gripped With Negative Lead Dabbing Numeral

6 - Etched Numeral In Progress
     At times emits smoke and hissing sound

7 - Numeral 3
     Stencil & tape removed and cleaned first
     with the vinegar/salt solution then the
     glass cleaner.

8 - All Ten Mags Etched

9 - Number Seven Etching Looks Good
     The manufacture must have buffed a production run of mags
     in a different direction or with a different method
     it looks polarized

10 - Fun Project
       I saw on the web how a guy used this method to
       mark the inside of his stainless steel cooking pot.  So I
       wanted to try to mark my mags so if I started
       having trouble with one I would know who the
      culprit was.  It was lots of fun.
