my step dad has given me his old model 54 sears 30-30, he can no longer hunt with his age and health. he told me only 3 boxes of ammo has been through it since he got it new many years ago. he only used wd40 on it all the years he had it and it jelled inside the magazine tube and action as he hasn't used it in several years. i got the jelled stuff out and it had surface rust on the outside magazine tube and just a little on the barrel but tube was the worst. i used flitz and a soft cloth followed by oil and 0000 steel wool. now i can run my fingers over the tube and everything is smooth but i can still see rust where it was. is there anythng i can use to remove this rust? is it as good as it can get without removing bluing? to close my eyes and run my finger it feels glassy smooth but rust can still be seen if you look. i don't want to reblue, the few spots of barrel rust are gone and left shiny spots and i'm good with that, just can't figure the tube out. thanks for any help.
