Birchwood Casey Perma Blue Paste (Model 13322) is a 2 oz squeeze tube cold gun bluing compound that produces a dark blue-black finish on bare metal. Unlike liquid blue formulas, it reacts more slowly to build a denser, longer-lasting finish, with full color achieved in multiple 30–60 second applications.
