i just bought a new pardner pump protector yesterday, while i was cleaning it i noticed something in the barrel about half way down. its about an inch long and goes completely around inside of the barrel where its at. i've used solvent and brush and left it over night and its still there. its not rust as when i dried the barrel it can be seen easily holding it to a light. its a thin film whatever it is almost like dried glue as it is just rough clear like, when pushing the cleaning patch thru it feels rough at the spot. just wondered if anyone else has ever had this problem?, gonna shoot it and see how it does. thanks
