Birchwood Perma Blue

Description

Birchwood Casey offers you the best way to touch up scratches and worn blueing,  even completely reblue most guns providing prep work has been carried out. Perma blue gives a non-streaky, even blue-black finish to steel (except stainless). Both Perma Blue® Liquid Gun Blue and Paste Gun Blue provide great blueing to metal that has already been thoroughly cleaned and is free of rust.
