Im going to blue my 1950's Mossberg 151k. I need some suggestions on a good quality blueing kit.

I like the perma blue kits by birchwood Casey, I did a mossy 500 with their stuff and it was easy and turned out great. I used the liquid not the paste.

[sharpshooter1997]

What method did you use to heat your barrel.

[cgersty]

It's a cold blue there I s no heat needed, just wipe on, let sit 45-60 seconds and rinse off with cold water, dry and repeat if finish isn't dark enough, blend together with steel wool then oil lightly and let cure for 25 hours and done.

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.

Cold blue doesn't work well for complete refinishes. It can promote rust, it stinks, and it offers no protection.
Paint your gun instead.

I really wanted to parkerize it, I took my time, degreased it, sanded all machine marks out of the steel, degreased again, used perma blue, then applied the barricade stuff to seal it, assembled gun, and lightly wiped down with oil, this gun sees the duck blind quite frequently and wiping it down with oil rag when finished and its held up without rusting for 2 waterfowl seasons so far, I had really good luck with it.

I have used Birchwood Casey Perma Blue on a couple of my sporter barrels. They turned out great. The trick is to follow the directions to a T. After smoothing out the final coat with steel wool, the secret is to really put the gun oil to it. I used the spray Rem-Oil. Spray it on, rub it in w/ a clean cloth and spray it some more and just let it set. Spray it again a couple of times a day for 2 days. Then lightly wipe it again and you are done. I got a pretty nice even deep blue.

I used birchwood casey cold blue on my SKS, it looks good but wears easily, which is actually a plus for me. I love the look of a used firearm.

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.
