I have found that "EEZOX" works best IMO on all the newly rust blued barrels and other blued parts that I do......

I also use EEZOX on all the case colored receivers that I do, NOT clear lacquer that scratches, peels and yellows.....

I also use EEZOX on all the internal parts during re-assembly as well.....

With multiple applications the "film" that EEZOX leaves coats the metal parts to near water proof and leaves a nice fingerprint proof permanent sheen .......
