Product Summary
The Birchwood Casey Perma Blue Cold Blue 2 oz Paste is a professional-grade solution for touching up scratches, worn spots, or completely reblueing most firearms. This paste provides a non-streaky, even blue-black finish specifically designed for steel surfaces. While it darkens more slowly than the liquid version, it is engineered to build up a denser and deeper finish over time. To achieve the best results, ensure the metal has been thoroughly cleaned and is completely free of rust before application.
