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 from Birchwood Technologies (Eden Prairie, MN) 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. According to the company, these 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. Additional features include:
- A chemical reaction that 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.
- The ability for the finish to be highlighted or distressed to achieve a distressed look. A final step to protect the finish and enhance the appearance is to add a clear topcoat such as a satin-gloss urethane lacquer or paste wax.
- A broad range of applications include building facade, fascia, elevator cabs, staircase railings and handrails, sculpture, monuments, and window hardware.
- Availability in 1 gallon and 5 gallon containers ready for easy application.
