I want to buy two officers size smooth arched mainspring housings. I was going to buy two S&As and remove the checkering. I found smooth arched housings on the Caspian website but they're titanium. Can you blue titanium or leave it unfinished?
Ti cannot be blued because there is no iron in it. Bluing is a form of rusting. Titanium can be anodized, but that will scratch. Heat coloring is also an option, and it will wear better, but you won't get a uniform color like you would get with anodizing. Bead blasted ti will wear much longer, but will give a muted anodized color. Just bead blasted ti has a dark gray look to it. When you wipe it with WD40 it will look even darker. Something that I have been wanting to play with is anodizing ti and then putting a clear coat of Dura Coat or Cera coat over top. That should wear better than any bluing.
