Customer brought in a Colt Python, someone had done a REAL nasty nickel job on her, and I mean nasty. He wants me to remove the nickel; which I have, and see if I can give her a nice bluing. Whoever did the nickel, used it to cover up some pitting on under lug on barrel; pitting on a scale of 1-10 about a 7.5, however it is a very small overall amount. I would like to fill it in, and if it can be done, a very high polish dark blue could be done. I have excellent high grade silver solder 97%+; has anyone had experience in this situation? Will it take a blue? We are only talking a few spots; but enough to be noticed. I'm concerned on using a nickel gas welding rod so near the barrel; although the under-lug is solid there, and it would be just a dab, then polish / buff out.
