I live and hunt in Southern Louisiana, therefore, myself and my gear are exposed to rather harsh conditions with the saltwater marshes. I've owned my SBE for 2 years now and due to regular usage I'm noticing a lot of wear of the bluing on the barrel. The most wear is at the muzzel end. I believe that this is due to the gun sliding in and out of its waterproof case. The case has a soft nylon lining, but it is still too abrasive. The gun has operated perfectly, but I think that it is time to get the barrel re-blued. Since the finish is the SBE matte black finish, how do I go about getting this done. Please help.
