Birchwood Casey Perma Blue Paste Gun Blue 2oz Tube MFG# 13322 UPC# 029057133226
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 Past Gun Blue is slower to darken than Liquid Gun Blue, but will build up a denser finish.
