Gels give metal a natural, aged appearance

Brush-on Presto Black® gel, Antique Black® gel, and Antique Brown® gel from Birchwood Technologies are designed for use on large, in-place architectural metal surfaces to produce a natural, aged appearance. Any size of vertical or horizontal metal surface can be converted to a silver/black wrought iron or antiqued finish look.

Suitable for use on most metal surfaces, including iron, steel, copper, brass, and bronze, the gels are applied at room temperature and stay where applied without runs, drips, or bleeding onto adjoining surfaces.
