And if you over heat the receiver to 2500F it could melt and burn you. And if you handle the torch improperly when you are applying your case color treatment you could damage the factory case hardening and the action could bend as you have made it soft again. The case hardening causes the action to bend like a spring and then return to shape. If you overheat it while torching it it will bend and not spring back. And if the kid at Quik-Change-Oil doesn't put the plug back in the pan correctly it could ruin your motor and perhaps leave you stranded on the side of the freeway where perhaps you could be accidentaly run over by an Oldsmobile 98 driven by Master Gunsmith Ed Landers.
But if the action is case hardened by a gunsmith competent in the use of the bone charcoal method the results will be good.
The safest way to put case colors on an old gun is to use a hobby spray gun outfit and paint them on. Probably no less garish or unsightly than what you are doing and perhaps as durable. And just as authentic.
Best,
Mike
