Our Midnight Black solution darkens steel and non-stainless steel alloys at room temperature without the need for any special equipment. This unique formula can be applied by immersion, spray or by brush for detailed areas. The color of the blackened surface may be burnished to lighten the intense darkness before sealing. After plating and/or coloring, finished parts may be quick dried and sealed, or allowed to oxidize. Oxidation will alter the colors and textures, creating an additional palate of finish effects.
