Birchwood Casey Super Blue - 3oz gun Blueing Liquid

Re-blued a rifle barrel. result was even better than I had hoped for. Echo the comment elsewhere on here about warming and oiling.

This amazing liquid puts an end to rust and corrosion. It is very simple to use and you can always do it again if needed. I don't owe a gun, but I use it for other steel parts, better than paint.

I have used this before on old guns. Extra help is:- Wash etc first. Then leave on a radiator until warm. Apply Super Blue and wash as required. When finished smother in oil and leave overnight for best results. It seems to absorb the oil but looks a lot better.
Price was good from Gamefish.
Downside is the smell on the metal after coating.

My air rifle was looking a bit sad so I spruced it up a bit using blue it was easy and with good results

I read various reviews about blueing solutions and this one seemed to be the most favourable. I wanted to re-blue my late grandfather's 1959 BSA Meteor Mk 1. I also needed to make a new rear sight for it out of mild steel. The results were excellent. It was so easy to use and the speed of the reaction was impressive. It hasn't made the gun look new but it has sympathetically enhanced the appearance to a massive degree.
With regards to the sight, after I had made it I treated it as well. It looks amazing and fits in with the looks incredibly well.
I would recommend this solution to anybody!
