Well prohunter, they did answer two of your three questions. The recommendation to clean the bore with their product and then protect the barrel with gun oil seems reasonable to me. The response about weathershield's purpose is factual, though they might have explained why it's not applied inside the bore. Don't know why they didn't answer your third question. We all know the answer is "no, the Bone Collector isn't available in stainless", but why not send the email back to them again and repeat the question. It would be interesting to see how they respond.
