I just finished making a couple of muzzle breaks and a fake silencer for my AR out of aluminum. Other than anodizing, is there a durable finish I can apply to aluminum, since thats what there made from. I tried airbrushing a flat black enamel paint. It looked really good but it comes off real easy
. Not what I had in mind. I don't have any where to anodize these parts without spending a good bit of cash which kind of defeats the purpose of making them myself.
