Product Description
Birchwood Casey Perma Blue Gun Blueing Paste
The longest lasting finish, but slower to darken than the liquid blues.
Easy-to-use, PERMA BLUE Paste Gun Blue reacts slowly with the metal but
builds up a denser finish that will outlast the liquid blues.
Excellent for touch-up or complete reblueing.
A dark blue color may require three or more applications of PERMA BLUE Paste
but each coat takes only 30 to 60 seconds to work.
Complete instructions on each tube. Apply with swab or “Q-tip.”
