yeah, definatly +1 on the mothers polish, i did all of my airgun barrels and they dont ever seem to lead foul anymore. Especially my mrod barrel, iv seen a great improvement in accuracy and i can go forever without cleaning and dont notice any reduction in performance. i run a bore snake though after i finish a 500 tin of JSB 18gr and thats about the extent of my cleaning for that gun. I highly encourage the metal polish after you clean your bore next time. then you can invest $7 in a bore snake and call it good for a few years. =)
