Immerse your parts or apply our gels to a sponge and blacken by hand!





Control the production of your parts with same-day professional in-house blackening at mid-temperature 225F! Get a gorgeous, rich finish that improves part appearance and increases sales appeal!

No boiling caustic fumes, provides a saver work environment, and saves on energy costs!
