Birchwood Casey Perma Blue Paste 57g Tube

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
