The bluing on the barrel is damaged by rust in several places.  Any suggestions for repairing (or re-bluing)? More worried about rust prevention than looks. Hot dip and fuming processes are probably outside of my abilities/resources. Doesn't have to be bluing - just something to prevent rust. |
DuraCoat might be an option. Little more complex to apply than regular spray paint but very much an easier DIY option when compared to re-bluing. DuraCoat sells DIY kits and there are plenty of tutorials videos on how to apply it. They also sell a coating called DuraBlue that is a spray on coating that replicates blueing.
