This cold blue paste formula penetrates deeper than liquid blues, producing a durable blue-black finish that resists wear and helps prevent rust on bare steel. Ideal for touch-ups on carry guns, hunting rifles, or refinishing projects where professional hot bluing isn't practical.\u003c\/p\u003e\u003cp\u003eThe kit includes Perma Blue paste, Cleaner Degreaser to prepare the metal surface, and Sheath rust preventative to seal the finish. Works on all steel surfaces—not recommended for stainless steel or aluminum. Apply with a clean cloth, let set, then neutralize and oil. Multiple applications build a darker, more even finish.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Cold blue paste refinishing kit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Materials:\u003c\/strong\u003e Carbon steel, alloy steel (not for stainless or aluminum)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKit Contents:\u003c\/strong\u003e Perma Blue paste, Cleaner Degreaser, Sheath rust preventative\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Cold chemical process, no heat required\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUse:\u003c\/strong\u003e Touch-ups, spot repairs, full refinishing of steel firearms\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Birchwood Casey","offers":[{"title":"Default Title","offer_id":47937363017983,"sku":"BC13701","price":18.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/1243134.jpg?v=1766486822","url":"https:\/\/doublestackstore.com\/products\/b-c-perma-blue-paste-gun-blue-kit","provider":"Double Stack Store","version":"1.0","type":"link"}
