I've been using black powder guns in one form or another since 1970. Most have got used every year, but not all. When I started it was hard to find some of the lubes and recommended oils. Several old timers told me to clean them, dry them, and seal them. Most used a good grade car wax, outside and on a swab down the barrel. I've followed their lead and so far my guns have held up to as good as or better then ones my friends purchased and used only recommended lubes on. My view for what it's worth, is get it clean and dry, and keep it dry, period!
