Bluing Perma Blue 90 ml - Birchwood Casey

Birchwood Casey Perma Blue quickly restores scratched and marred steel areas. It is important to use a good degreaser before applying the liquid. The color will vary from deep gray to black depending on the alloy.

Traditional hot blueing methods work best where major work is required but for minor areas this product is an inexpensive, viable and easy to use alternative.
