Perma Blue™ Gun Blue Cleaner by Birchwood Casey®. Liquid. Volume: 3 fl. oz./ 32oz/2oz Paste 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.
- This is a Special Order product and, therefore, Non-Cancellable and Non-Returnable
