Precision Bluing
CARE FOR THE NEWLY-BLUED
The bluing process on steel is a true conversion coating,
meaning that the surface has been changed into something else. The process in hot salts converts the ferrous
metal surface into a black iron oxide compound called Magnetite (Fe3O4). The magnetite is quite porous and to prevent
moisture from penetrating and causing rust, a seal must be applied and
maintained. A good oil or wax must be
applied with a lint-free, soft cloth.
Fingerprints should be wiped off and the surface resealed after each
handling. Every time a metal part is
touched, a portion of oil is removed leaving the surface unprotected and
vulnerable, subject to rust.
By keeping
an oily cloth in a small covered container in your gun cabinet and making it a
habit to wipe your gun down after every handling, you can increase the
longevity of the bluing on your guns.
Never put a moist gun in a gun case for storing! Very expensive guns have quickly turned into
a pile of flaky rust by people making this mistake!
Humid weather is another enemy. Pick the driest spot in your home to store
your guns and protect them by cleaning and oiling them regularly.
When bench shooting, always rest your gun on something soft
to avoid scratches. Avoid scratching any
surface. If micro rust should form, 0000
steel wool with oil will remove it, however, do not let it become too
extreme.
There is a point with rusting
when the only cure is rebluing.
