Will JB Weld take cold blue?

[Rick O'Shea]

I need to do some cold blue touch-up on a small area of a revolver cylinder.

The gun was apparantly laid on its side for a while and there is a small patch of rust pitting where the cylinder was in contact with the surface.
I've already very gently rubbed off the high areas with ultrafine oil-soaked steel wool -- just to the point of wearing off the original blue.

The area is still rough, and it's from the recessed areas - the pits. I don't want to take the metal all the way down to the bottom of the pits to smooth it, so I thought about using something like JB Weld (love the stuff!) to fill it in.

Anyone ever try something like this? Will cold blue darken the metal in the JBW?
Is there a best (or at least better) way to approach this?

All suggestions are welcome.

Thanks,
Rick

Blueing epoxy

JB Weld is an epoxy. It will not blue.

 

[Winger Ed.]

The Brownell's catalog lists some type of silver solder that will blue with the common chemical type bluing. But there's no way it would be a exact match.

For a experiment, get 4 or 5 different pieces of steel. Bolts, bar, whatever, and blue them,,,,,,,, they'll all have a slightly different shade no matter how much you fuss with the blueing stuff.

If the pitting is small, I've heard of folks filling the pits in with a #2 lead pencil. Then rub the part off with a oily rag. You have to touch it up periodically, but it looks about as good as any patch for pitting, and you won't end up sanding off the rest of the factory blueing.

I was looking to see what JB Weld is filled with, didn't find it. I did find this.

Interesting stuff, watch the movie. The parts they're fixing are high pressure stuff which has to be very tough. If they're not BSing that repair material would rock. I hate the colors though.

You might consider filling that in with the Duracoat filler and then completely refinishing the revolver with Duracoat. You could go for a two tone and fill and refinish just the cylinder in a different color leaving the rest alone. Hey, it would look better than the uglified 'cowboy' guns they're selling that are fake corroded.

Thanks for all the replies, everyone.

I don't want to do anything drastic here; this is a beautiful old K-22, and the rest of the finish is fine.
I guess that's why this little rough patch bugs me. But that's all it is - a little rough patch.

If the JB Weld won't take blue, then I'll either find another solution or leave well enough alone.

Thanks again for the advice,
Rick
