Im going to blue my 1950's Mossberg 151k. I need some suggestions on a good quality blueing kit.
All the cold blues wear easily.
There is always someone who thinks they have found the magic formula for applying it. And, they think it looks great-but any gun pro can tell a gun has been cold blued very easily. And it's still stinky, copper sulphate, easy wearing, rust-enhancing cold blue.
MOST cold blues will do better on WARM steel than cold.
Polish the barrel really good- degrease- warm with a blow dryer, do not touch with bare hands. I use a new toothbrush to apply bluing. BlueWonder does well, as do the Birchwood Casey products. I also keep a bottle of Van's 44-40 because it works great on SOME steels.
Agree on all thatIf you do not have it in a kit, bluing can be removed with bluing remover- or phosphoric acid. If you do not have a complete chem lab that you can walk down and snag an ounce or two- check your local hardware store for a product called Naval Jelly.
Or loan the gun to your brother-in-law. It will come back missing half the bluing.
