I am so angry right now...and need you all help! I was prepping my rifle (marlin 444) for hunting season and noticed some rust. I grabbed my rust removal and applied...then noticed the blueing coming off! I grabbed the wrong *#&$ one...took off the blueing! OMFG!!! So now I have the barrel about 1/3 or 1/2 with blueing taken off! UGG!!! Haven't blued before and was wondering how hard...what to use...should I take it all apart or should I just get a gunsmith to do it? If gunsmith how much does it usually cost? Steps if I do it myself? Product? HELP!!!!
