Newly Blued firearm rusted in under a week
Q. I just finished blueing an old 30-30 -- it came out looking great. I let it sit for 24 hrs and then polished it with 00 steel wool
⇦ this on
eBay or
Amazon [affil links] and wiped it down with Barricade ⇨
several times and then put the gun away in my safe, a week later (today) I wiped down the gun and found a lot of rust. How do you stop the rust?

A. Factory "blueing" is actually black oxide, applied at 290° F. Whatever you did at home is something else - it is not the same as, or equivalent to, factory blueing.
There is a reason that factory guns are done by the hot black oxide process. It is superior.
Most of the imitation processes intended for amateur D-I-Y use leave a brownish residue which will wipe off.
You should direct your inquiry to the mfgr of the product you used.
