Description

The TetraGun Liquid Blue Blister Pack (F002I) contains a high-quality cold bluing agent formulated to restore and enhance the blued finish on steel firearm and airgun metal components. This liquid creates a chemical reaction with the metal that produces a durable, dark oxide layer, improving appearance and offering corrosion protection. Its non-streaking formula works equally well on minor scratches, worn areas, or an entire surface, and can be layered up to seven times to achieve the desired darkness. Easy to apply and consistent in performance, this trusted bluing solution is widely used by gunsmiths, collectors, and shooting enthusiasts for both touch-up work and full refinishing projects.
