I chose to Cerakote a K frame recently but for various reasons I was not fond of the gun in its then configuration so I'm having a bunch of customization done on it. It was a $350 gun when I bought it and after I finish paying for the custom work I'll have almost three times in it than it's worth because for someone else it's likely still a 300 dollar gun. But it was not a 100 year old classic and there are probably plenty of others like it around. A classic old gun I would not Cerakote.
