Description
Birchwood Casey Spanish Perma Blue Liquid Gun Blue offers you the best ways to touch up scratches and worn spots or even completely reblue most guns. It will give a non-streaky, even blue-black finish to steel (except stainless). Perma Blue provides great blueing to metal that has already been thoroughly cleaned and is free of rust. Please note: Perma Blue Liquid Gun Blue will not blue stainless steel, aluminum, or non-ferrous metals.
