Store aerosol at room temperature for 2 hours prior to use. Shake can vigorously, in a vertical motion, until the agitator ball is heard and then for a further 3 minutes. Apply light even coats, from a distance of approximately 15cm (6 inches) and keep the aerosol moving. Do NOT concentrate spray in one spot. Apply 3-4 coats for maximum protection and allow 15 minutes between coats. Between coats invert can and spray for 2 seconds to avoid blockages.
