Since I have so many mags,this makes it easier for the old man in me to identify them Takes only a few minutes to prep,and finish..
Well, it actually is rather an easy process. You need a to get a few things to make the job nicer. 1 NON acetone fingernail nail polish remover DO NOT use Acetone remover! 2 cotton balls 3 Nail polish (I prefer White Art Deco you get at Dollar tree etc) 4 clear nail polish 5 plastic razor blade(WalMart, Lowes) Take a cotton ball and put some acetone remover on it and rub it into the Glock insignia, caliber and the numbers. Let dry completely. After it dries, I use another clean cotton ball and wipe it off to make sure it's clean. Take your color you desire to use of nail polish and dab some on all spots and let sit.Careful not to get in the holes you use to see if loaded ammo is to that point. After it dries,take plastic razor and lightly remove the excess polish. You can even lightly scrub the mag and remove the excess if you are careful. If you need touch up,do a light 2nd coat. After you have removed the excess and clean it up,be careful and give it a light coat of clear polish. Let dry and use another cotton ball with acetone to ligtly clean it.You are done then. Takes about 20-25 minutes depending on how many and dry time. Makes identifying easier as well
Using wax crayons also does the trick. Wouldn't be as permanent as paint but easily applied and any surplus wiped off.
That was my way when I first did it. But Texas heat and getting the guns hot would melt out. The fingernail Polish or model paint is much better.
