You need to get rid of the rest of that rust before it pits the barrel. Some #0000 steelwool and a good gun oil will get the rest off there. Treat it with a good rust preventive oil or gun grease to keep it from getting worse. Honestly if it were mine I would have it reblued, and not cold blued, hot blued and before those spots become pits!

Hot blue isnt really something you want to do at home, the set up and supplies are very expensive for the average person just wanting to do the ocaissional gun. Most of the companies today use a hot salt bluing that comes out black. The orignal finish on that rifle would have been dark blue. It could be expensive to get it back to orignal finish and look. If you just want to reblue it and make it look good again Craftguard is a real good company to deal with. They wont polish out the stamping on the rifle, like some companies Ive seen over the years. And if you take it apart and just send them the parts to polish and blue their fairly reasonable on price, and their pretty quick on turn around time. Now if you want it to be orignal for the collectors value Id give Remington a call and see what they say on refinishing it there.
