Birchwood Casey offers you the best ways to touch up scratches and worn spots or even completely reblue most guns. It will give a non-streaky, even blue-black finish to steel (except stainless). Both Perma Blue Liquid Gun Blue and Paste Gun Blue provide great blueing to metal that has already been thoroughly cleaned and is free of rust. Perma Blue Paste Gun Blue is slower to darken than Liquid Gun Blue, but will build up a denser finish. NOTE: PERMA BLUE Liquid Gun Blue will not blue stainless steel, aluminum or non-ferrous metals.


Q: Why is the Perma Blue, Super Blue, or Presto Mag not taking to the metal?
A: The chemical will not take to a metal that is not 100% steel. To confirm if you metal is steel place a magnet directly onto the metal. If the magnet does not stick the material it is not steel. Another reason that the chemical may not take to the metal is that it is not fully clean. For the best results use Birchwood Casey Cleaner-Degreaser. If you do not have access to it, ordinary dish-washing liquid soap will work as a substitution.

Q: How many coats of Perma Blue or Presto Mag can I apply before it will not get any darker or better?
A: After 3-4 coats the metal will not get any darker or better.

Q: How do I apply Perma Blue, Super Blue or Presto Mag?
A: Apply chemical cold using cotton swabs, synthetic brush or sponge.
