Shake can for at least two minutes after ball is loose (agitator ball may stick to bottom of can for some time). Apply a uniform coating, holding can 10-12 inches away from surface area. Multiple coatings are more effective. Allow 15 to 20 minutes drying time between coats. Do not apply closer than 10inches to the exhaust system. Do not apply at temperatures below 50°F. Use mineral spirits or kerosene for cleanup. After use, invert container and discharge in order to clear valve and actuator of residue.
