Like all Birchwood Casey products that I have used, this Presto Gun Blue works as advertised, it gives a light grey to bluish color to the metal. I used it on some 1084 high carbon knife blades for rust prevention and achieved the result I desired after one application. On firearm parts, you would probably need multiple applications, with a light polish with fine steel wool between coats, to match the existing shade of blue. Overall I would give it a big thumbs up for ease of use and quality of finish.

I am using this product to rust proof some small lathe tool holders I made. The instructions are easy to follow and the resulting finish is as expected. I might try using wider swabs so as cover a larger area with each swipe.

Deixa sua arma e faca azul negro. O ideal é lixar bem até a lixa 3000 e após lavar bem passar Álcool combustível e depois de seco aplicar sem fazer força. Repetir a aplicação passando palha de aço bem fina. E depois dar um polimento e lubrificar. Excelente produto.
