960ml bottle

- A double-strength blueing solution designed for blueing highly polished steel parts and hardened steels containing nickel and chrome alloys (except stainless)
- Super Blue Extra Strength Gun Blue is the blackest blue
- Use caution to confine the solution to the area to be reblued, as it will have an effect on the existing blue
- For blued steel and black anodized aluminum, the industrial formula remains permanent against most solvent/chemical washes
