I've been cerakoting a few of my rifles,so far just unfluted barrels. Now I want to coat one of my rifles that is fluted and I want to make the flutes a different color. I've been tring to figure out how to go about that. Right now I have two thoughts, first is to fill the flutes with clay spray the barrel, strip out the clay and then tape off the barrel and spray the flutes. I'm just concerned that when I bake it the clay will contaminate the coating. My other thought is to spray the whole barrel bake it, the tape off the ridges bead blast the flutes and then coat the flutes. If anybody has any other ideas or has done this I would apprieciate some advice. Thanks in advance.
