I know there are a lot of different ways I could or should have done this. And I may before it’s over with. Cerakote or Black oxide or nitride beforehand would have been good. I really don’t want to remove the barrel from the action. My goal is simply to cut the shine of the polished stainless barrel. It gives off too much reflection when hunting. Looks are secondary here. I‘m more concerned with function. My plan is to rough up the stainless, clean with Acetone, then use a dark olive self etching primer. Then follow that with either an olive drab or matte Black top coat. Or a camo coat. I know I would need to protect the muzzle and crown. My question is. Is the use of self etching primer ok?
