Sold in a convenient \u003cstrong\u003e3 oz plastic bottle\u003c\/strong\u003e, this fast-acting liquid goes on evenly and cuts the time needed to bring a tired-looking gun back to a deep, rich blue-black.\u003c\/span\u003e\u003c\/p\u003e\n\n\u003cp\u003e\u003cspan style=\"font-size: 14pt;\"\u003eApplied to a properly cleaned and degreased steel surface, \u003cstrong\u003ePerma Blue Liquid\u003c\/strong\u003e chemically converts the top layer of metal to deliver a uniform, non-streaky \u003cstrong\u003eblue-black finish\u003c\/strong\u003e that closely matches traditional factory hot-bluing. Swab a thin, even coat onto the part, allow the reaction to develop, then neutralize and oil the surface for a long-lasting protective finish. It is equally at home refreshing small parts like screws and trigger components or tackling larger surfaces such as receiver sidewalls, barrel bands, and sideplates.\u003c\/span\u003e\u003c\/p\u003e\n\n\u003cp\u003e\u003cspan style=\"font-size: 14pt;\"\u003eThis \u003cstrong\u003e3 oz Birchwood Casey Perma Blue Liquid Gun Blue\u003c\/strong\u003e (model \u003cstrong\u003e13125\u003c\/strong\u003e) is suited for virtually any blued or unfinished carbon-steel firearm component, making it a handy addition to any gunsmithing bench or restoration kit.
