Gun corrosion is a serious problem that can lead to major problems with the usability of your firearm. To prevent this, use a proper gun corrosion prevention method from Zerust. To prepare guns and rifles for storage, first clean and cool the weapons. Then cut a Zerust Tube and Barrel Strip to the desired length, slip it inside the barrel, and cap the barrel shut. Keep your sight on target by preventing corrosion you can’t see with the naked eye.
