Yep, it's fun discussing stuff like this. I have grave doubts about the efficacy of this type "repair" but if Mike's willing to give it a go I'm all ears as to the results.
I doubt if Mike, or anyone else here, would try to salvage, in this way, a barrel that was deemed unsafe because of extreme pitting. I certainly wouldn't. If it were to last for any considerable length of time it might spark an idea for a repair on something else one day down the road, that we would never have thought of otherwise.
If it doesn't last indefinitely it doesn't mean the idea was a failure. It just means that potential method/product has been eliminated by actual trial. That's often how useful discoveries happen.
