{"product_id":"birchwood-casey-perma-blue-paste-gun-blue-2oz-1","title":"Birchwood Casey Perma Blue Paste Gun Blue, 2oz","description":"Birchwood Casey Perma Blue Gun Blue Paste is for touching up scratches and worn spots or reblueing most guns. It leaves an even, streak-free blue-black finish on steel that is clean and free of rust. Compared with the liquid version, the paste darkens more slowly but builds up a denser finish. Apply it cold with cotton swabs, a synthetic brush or a sponge; three to four coats give the darkest result. It only works on steel, so it will not blue stainless steel, aluminium or non-ferrous metals, and ordinary washing-up liquid can be used to get the metal fully clean first. 2oz.","brand":", Export_Restrict: True , Export_Block , LS-RM Default , H437","offers":[{"title":"Default Title","offer_id":45226809426120,"sku":"S195589","price":12.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0071\/8906\/9860\/files\/LIt8uwwNgmYNgfN9GKjXxEcDjCacsecZ-35.jpg?v=1790940631","url":"https:\/\/www.bushwear.co.uk\/products\/birchwood-casey-perma-blue-paste-gun-blue-2oz-1","provider":"BushWear","version":"1.0","type":"link"}
