Im cerakoting the barrel on my rem 700 tonight.. I was wondering if I should tape off the top of the action where the scope rail bolts to the gun.. So its metal on metal.. Or is it OK to just have the cerakote between the two.. I know cerakote is pretty thin.. Shouldn't be a problem right?? I know u should not do the inside of scope rings.. Thats common sense.. But I wasn't sure about between the action and rail... Any help would be rad..
