Limitations
Bluing only works on steel or stainless steel parts for protecting against corrosion. Because it changes the Fe into Fe3O4, it does not work on non-ferrous material. Aluminum and polymer parts are largely unaffected by bluing; no protection against corrosion is provided by bluing processes on them, although uneven staining of the aluminum and polymer parts can be caused by attempts at bluing.
Holster wear will remove hot bluing, rust or fume bluing over long periods of use; it will remove cold bluing over relatively short periods of use, from any wear areas that are "touched up" with cold bluing solutions.

Famous quotes containing the word limitations:
“Much of what contrives to create critical moments in parenting stems from a fundamental misunderstanding as to what the child is capable of at any given age. If a parent misjudges a child’s limitations as well as his own abilities, the potential exists for unreasonable expectations, frustration, disappointment and an unrealistic belief that what the child really needs is to be punished.”
—Lawrence Balter (20th century)
“... art transcends its limitations only by staying within them.”
—Flannery O’Connor (1925–1964)
“That all may be so, but when I begin to exercise that power I am not conscious of the power, but only of the limitations imposed on me.”
—William Howard Taft (1857–1930)
