Hi!
I built a vampire killing kit about 6 months ago which includes a nice working percussion pistol replica from Dixie Gun Works. I used Birchwood Casey Plum Brown to finish/age/weather it as per the instructions and I was very pleased with the results:

A few days ago, I reopened the bottom layer of the case and took out the pistol and was shocked to see how rusted the iron parts were! I am sure, now that I think it over, that this comes as no surprise to experienced gun owners, but I really did not expect it to be this severe. I then set about patiently disassembling the pistol and working oil into all of its parts while trying to preserve the antique appearance. I have definitely lost a lot of metal off the more delicate parts but everything works again I am satisfied with the appearance.
How can I arrest this process without changing its appearance too much? Is coating it, inside and out, with a thin film of oil the best approach? What oil should I use?
I live in the mountains of Virginia and it is not displayed in a particularly humid area (air conditioned, etc,) but should I include some of that rust preventing paper like they use in tool boxes in the kit (just between showing it to people)?
Thanks for your advice,
Steve Harris
