Koldblak Gun Blue
- Creates a protective black oxide coating on steel surfaces
- Ideal for guns and tools, leaving an attractive finish
- For use at room temperature – The safer alternative to hot caustic processes
- Simple and economic to use – Ideal for small and large volume users
- Once treated it creates an ideal surface to absorb wax, oil or other rust-preventative sealants to give superior corrosion protection
- The coating is integral with the surface, meaning there is no dimensional change
- Made in Britain
The coating produces a protective black oxide coating on steel that is integral with the surface, meaning there is no dimensional change. Koldblak is the safer alternative to the traditional hot caustic processes and is ideal for small and large volume users alike.
*Not for use on Stainless Steel
Remove all traces of oil or grease. Remove old paint and loose rust with steel wool or wire brush.
1. DEGREASE: Ensure that the surface is completely free from rust & corrosion. Once this has been achieved the material should be degreased using solvents.
2. MIX: Using a plastic container, mix a solution of Koldblak with 25% concentration (three volumes of water and one of koldblak) at room temperature (15-25°C). Once mixed, immerse the item for a period of 5 – 15 minutes.
3. RINSE & FIX: Remove all traces of oil or grease. Remove old paint and loose rust with steel wool or wire brush. Fix the black finish by treating the part with an oily protective product.
4. PROTECT: Once dry, you can protect the finish using a water repellent of your choice, such as paraffin wax or an alternative oil-based product. The blackening layer fully cures after 24 hours.
Consult the safety date sheet before use. Not for stainless steel.

Rust Converters chemically transform rust into a protective layer, stopping corrosion and preparing the surface for further treatment. Rust Removers, in contrast, directly dissolve rust, returning metal to its pristine...
