4. Brush It On
Unless you're an expert with a spray painter such as artists use, refresh the paint jobs on decoys with a flat brush. In most instances, ¼, ½- and 1-inch brushes will do. The smaller brushes will work for the eyes and bills, rings, wing patterns, blotches, and that sort of thing. If spray paint is used in some instances because the area to cover is so large, make sure it has a fan-shaped applicator.
