Birchwood Casey™ Perma Blue Liquid Gun Blue 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.

Birchwood Casey™ Perma Blue® Liquid Gun Blue comes in a 3 oz. plastic bottle. The bottle is the best way to touch up scratches and worn spots or even completely reblue most guns.  

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