Brush-on Presto Black® Gel, Antique Black® Gel, and Antique Brown® Gel are the perfect solutions for use on post processing part touchup or on manufactured metal parts not suitable for traditional processing lines. Without runs or drips parts can be quickly touched up on any surface in vertical or horizontal position.
Ideal for most metal surfaces including iron, steel, copper, brass, bronze and other metals, the Presto Black Gel, Antique Black Gel, and Antique Brown Gel are simple and safe to use. Applied at room temperature, the gel adheres to vertical surfaces and stays where applied without forming runs or drips or bleeding onto adjoining surfaces.
These new Gel finishes are the perfect solution when you can't or don't want to dip the entire part into a liquid bath container. They're great for sheet metal that needs only partial blackening, for touching up parts and for adding finish to machined components.
The Presto Black Gel, Antique Black Gel, and Antique Brown Gel chemical reaction takes only 5 to 10 minutes following surface cleaning to remove oil, oxides and welding flux. Color tone and depth is easily controlled by visual inspection and stopping the process by rinsing off with a wet sponge and sealing the finished surface. It's that easy.
