An apparatus and method of applying a finish or paint coating in a prefinishing or finishing line to a fencing panel or picket that disguises the screen-back texture of the engineered wood substrate. After paint or similar coating is applied (such as by one or more spray nozzles) to a face to a fence picket or fencing product or component, the fence picket passes under a roller, brush, or roller brush or similar paint applicator while the paint is still wet. The roller/brush removes some of the paint and applies an angled pattern to the face, which disguises the screen-back texture of the substrate.
