Birchwood Casey™ Perma Blue Liquid Gun Blue Kit is perfect for blueing your new muzzleloader rifle kit barrel. Perma Blue® Liquid provides a non-streaky, even blue-black finish to your steel barrel or receiver. Birchwood Casey™ Perma Blue® Liquid Gun Blue delivers an outstanding blueing finish to metal that has already been thoroughly cleaned and is free of rust. Unlike Perma Blue® Paste Gun Blue, the Birchwood Liquid Gun Blue is quicker to darken and has a less opaque finish.

The Birchwood Casey® Blueing Kit is easy to use and has everything you need to blue your barrel properly. The Liquid Perma Blue™ is a fast-acting liquid gun blue that gives you a smooth, even finish.  The kit contains everything you need for a professional-looking, world-class barrel finish.

**PERMA BLUE® Liquid Gun Blue will not blue stainless steel, aluminum or non-ferrous metals.
