A clean dry surface free of scale, corrosion, dirt, grease, oil, marine fouling or other foreign matter will provide the optimum performance of this paint. Be sure to remove all dust, debris, and other surface contaminants generated by the cleaning process prior to painting. Inadequate surface preparation will result in unsatisfactory performance. Bring to room temperature (close to 72°F) before spraying. Shake can for 3 minutes listening for mixing ball.
