Presto Mag Liquid Gun Blue Pen
Best for quick, on-the-spot touch-ups on non-stainless steel surfaces. This compact pen dries fast and provides instant penetration, delivering a durable blue-black finish that resists rubbing off. The fine tip enables access to tight areas, making it ideal for field maintenance or a stray nick you want to seal immediately. Limitation: not recommended for stainless steel unless the product specification allows it, as results may vary on different alloys.
Oxpho-Blue Liquid Gun Blue
Best for achieving an even, professional blue-black finish with straightforward application. Oxpho-Blue is a cold bluing solution that requires only dampening a cotton flannel and rubbing the area to be treated. It’s well-suited for larger touch-ups and rebluing jobs where uniform coverage is desired. Limitation: the process typically requires careful prep and may require repeated applications for deeper blueing on larger areas.
Birchwood Casey Perma Blue Liquid Gun Blue Kit
Best for an all-inclusive touch-up and reblue project. This kit includes a cleaner/degreaser and Perma Blue liquid for a non-sticky, uniform blue-black finish after proper preparation. It’s ideal for gun owners who want a complete solution in one package, enabling both cleaning and finishing in a single workflow. Limitation: the kit requires thorough cleaning prior to applying blueing to achieve optimal results.
Birchwood Casey Long-Lasting Fast-Drying Touch-Up Pen
Best for deep scratches on receivers, triggers, scopes, and sporting accessories. This flat-black pen provides quick application, is easy to carry, and features a fast-drying, lead-free paint with a precise tip. Limitation: it’s a touch-up tool rather than a full reblue solution, so deeper or larger areas may benefit from a full reblue process.
Birchwood Casey Perma Blue Liquid Air Gun Blueing
Best for air guns and shotguns requiring a fast-acting, even blue-black finish on metal cleaned of rust. It offers a reliable method to touch up or reblue on non-stainless steel and pairs well with a prep routine that removes residues. Limitation: results can vary based on blade hardness and metal preparation, so a careful degreasing and rust removal step is essential.
