Why buy base coat and a top coat when you can get all the benefits in one product? Double Duty is a combination of base coat and top coat that hydrates and seals the nail bed. It can be used as an extremely durable top coat over your favorite Sally Hansen nail enamel.
Shake gently. First, apply to clean, dry, bare nails as a base coat and let dry. Brush on 1 to 2 coats of your favorite Sally Hansen protective nail color and let dry. Finish with Double Duty as a shiny top coat.
