{"product_id":"b-c-super-blue-liquid-3oz","title":"Birchwood Casey Super Blue Liquid 3oz – Cold Blue Touch-Up Solution","description":"\u003cp\u003eBirchwood Casey Super Blue is a liquid cold blue solution formulated for touch-up work on steel firearms. It chemically bonds to properly cleaned and degreased steel surfaces, restoring bluing on worn spots, handling marks, or scratches. This is not a hot-tank blue—it's a room-temperature chemical application designed for small repairs and refinishing work, not complete rebluing jobs.\u003c\/p\u003e\u003cp\u003eThe 3oz bottle includes an applicator swab for precise control. Works on carbon steel and alloy steel surfaces. Surfaces must be thoroughly cleaned with a degreaser and prepped with Birchwood Casey Blue \u0026amp; Rust Remover or similar cleaner before application for proper adhesion. Not compatible with stainless steel or aluminum.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Cold blue liquid (touch-up)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBottle Size:\u003c\/strong\u003e 3oz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Materials:\u003c\/strong\u003e Carbon steel, alloy steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Room temperature chemical process\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUse:\u003c\/strong\u003e Repairing worn bluing, scratches, handling marks\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eSafety:\u003c\/strong\u003e Contains selenious acid.
