Gun barrels can be parkerized by submerging them in a vat of boiling water mixed with sodium hydroxide (lye) for about 20 minutes. The sodium hydroxide etches the metal surface, creating an ideal surface for the parkerizing chemicals to adhere to.
After etching, the barrel is rinsed with cold water and then dipped in a vat of hot paraffin wax. The wax helps to seal in the parkerizing chemicals and protect the metal from corrosion. Finally, the barrel is allowed to cool, and then it’s ready to use.
Parkerizing is a great way to protect your gun barrel from corrosion and wear, and it’s also very affordable. You can find parkerizing kits at most gun stores, or you can order them online. Many companies offer parkerizing services if you don’t want to do it yourself.
