Perma Blue Paste reacts gradually with metal to create a deeper, denser finish than liquid blueing products. It takes
longer to darken than other products each coat takes between 30 and 60 seconds but the results are
undeniably superior. A dark blue color may require three or more applications. Ideal for touch-up work or complete
reblueing. Apply with cotton swabs. Metal must be cleaned and rust-free before application, then sealed with a rust
protectant. Complete instructions on tube. Weight 2 oz.
