Tap bottom of can to loosen agitator ball. If ball does not loosen, shake can until agitator ball is heard. Shake can for at least five (5) minutes after hearing agitator ball. For best adhesion, apply only to clean, dry surfaces. Apply a uniform coating, holding can 10 to 12 inches from surface. Multiple thin coats are most effective allowing 15 to 20 minutes between coats (shake well before reapplying). Allow to dry for 24 hours. Avoid application of any undercoating or rust proofing materials closer than 12 inches to any part of exhaust system or catalytic converter. NEVER spray directly onto exhaust system or catalytic converter. For cleanup, use mineral spirits or kerosene. This product is NOT considered paintable.
