How do you refinish a barrel on a 312 benjamin air rifle?

Answer 1

I think you mean re-blue the barrel. "Birchwood Casey" makes gun bluing products. You can even do touch-up or complete bluing.

I suggest you remove the stock then use a "bluing and rust remover." Afterwards I used a very light Steel-wool (#0000) and then wiped it down and got all the steel fuzz of the rifle. Wear plastic gloves you don't want to get skin oil on the barrel or bluing on your hands. (it stinks) I wiped it down with a damp cloth, when it was dry I made sure it was a clean as possible. I used an air hose to blow everything off the barrel. Then I took a very soft cloth and applied the bluing. It will take several coats. But it turns blue all of a sudden as you are applying it. It gets darker as you apply additional coats. I used a small paint brush to make sure I got it into all the creases and joints.

I suggest you practice on a piece of metal first to get the Idea. You can purchase everything you need at Cabelas, Basspro, Big 5 or any firearms dealer. Birchwood Casey also makes products to redo your stock.
