Gun Liquid Blue | Tetra Gun – cold bluing solution for metal surface protection

Tetra Gun Liquid Blue is a liquid bluing compound designed for cold bluing metal surfaces on airsoft replicas and firearms. This 80ml maintenance product creates a protective oxidation layer that prevents corrosion and extends equipment lifespan, suitable for treating scratches or applying complete new bluing.

Construction and materials

The solution creates a chemical reaction with metal surfaces, forming a dark oxidation layer that protects against moisture and oxygen. The non-streaking formula ensures even application without spotting. Multiple layers can be applied – up to seven – to deepen the colour and strengthen protection. The enhanced formula includes a new additive that produces richer colour while reducing treatment time.

Application and use

This bluing solution treats wear marks, scratches, and pitting caused by intensive use on metal components. It's designed for maintenance of airsoft replicas and suitable for firearms, providing both cosmetic restoration and functional protection. The 80ml volume provides sufficient product for multiple treatments or complete replica refinishing.

Integration and compatibility

The product is compatible with all metal parts requiring bluing treatment or restoration. It works on various metal types commonly found in airsoft replicas and firearms. The white liquid applies easily to targeted areas without affecting surrounding materials or finishes.

Maintenance and lifecycle

Regular application maintains the protective layer and appearance of treated surfaces. Reapplication may be necessary after heavy use or when wear becomes visible. Store the product sealed to maintain effectiveness between applications.
