Hello, new to this forum, looking to antique a double coach gun. Saw an article on "gunblast" for antiquing a SA pistol, but what would be an easy way to do a double shotgun?
What exactly do you want to do?
For the brass, when using real black powder, I just wipe dirty cleaning patches on the brass. It doesn't take long to get 'antiqued'. For the wood you might have to strip and refinish. If you won't tell anyone my "secret" finish for making guns look antique is Kiwi brown paste shoe polish.
There are a number of ways to remove bluing but I'm sure you would want to control the areas of removal and feather it. That would replicate normal wear. Not too far back, there was a post in here where a fella wrapped a rag around a barrel and applied vinegar. Gave it a tie-die look and did remove the bluing. I'm not suggesting this procedure, just pointing out that you can use vinegar.
Do a historical search in here to read how he did this. ....
As far as brass, again there are a number of ways. I routinely refurbish ramrods and on the brass tips, I rough finish with scotch brights and apply regular bluing. It turns brown, instantly. Will wear off but hold until a natural oxidation can take root. ....
GasMan,
The one I'm refering to is the fellow who wrapped his barrel with rags, then soaked them with vinegar and let it sit a spell. Posted pictures showing the pattern that was left. At any rate, you now know about vinegar. ....
I think I would identify the areas that would normally show wear after a time and work them manually with an abrasive. Post some pictures when you are done. ....
Why speed up a natural process? The best way is to use it. Brass will naturally discolor and the bluing will naturally wear off if you shoot and clean the weapon.
