Once anodized, your 80 lower can easily be dyed at home! You can find numerous at-home dye kits to produce a hard, flat, baked finish that's identical to a Type III Hardcoat finish. Submerge the lower in distilled water to neutralize remaining acid. You should see a nice platinum or bronze tone appear. The current can then be terminated, and the lower removed to inspect the anodizing process. The lower must remain submersed in the solution for at least 1 hour and 15 minutes. Apply current through the cathode and anode using the battery charger or power source.Īt this point, you're anodizing! You should see fizzing occurring in the solution.Connect the negative terminal of the battery charger to the aluminum cathode extension.Connect the positive terminal of the battery charger to the aluminum wire.Submerse the lower receiver into the solution with the aluminum wire. Tightly wrap the extension around the aluminum foil cathode.Create an extension of aluminum foil, in similar fashion to the ring, long enough to protrude to the top of your tub or tray.The ring should be large enough to surround the receiver by about 3"" to 5"". Create a tightly wrapped, round ring approximately 1"" thick, using aluminum foil.Leave enough wire to safely protrude above the tub or tray. Wrap a loop of aluminum wire tightly around the lower receiver.This will help to produce a better finish. OPTIONAL: Surround the container in ice to lower the solution's temperature.Fill a clean polyethylene tray or tub with sulfuric acid and distilled water.It must be completed free of surface contaminants, grease, and oil. Current is then applied using a battery charger and the oxidation process occurs, coating the raw lower with an anodized finish! You must wear gloves, a face mask, and proper eye, face, and body protection during this entire process: This process involves creating a cathode (negatively charged aluminum foil) and an anode (positively charged lower receiver), and submersing the pair in a solution of sulfuric acid and distilled water.
