Before you apply the finish coat, consider the following: Available staging and light--you can never have enough. Temperature of the paint, boat, room, and expected cure time--make sure they match the manufacturers recommendations to the tee. Make sure you have the proper tools: roller pan and frame, brushes, high-quality masking tape, etc. Minimize dust, bugs, and airborne debris with proper ventilation. Consider the number of coats youll need, and how much dry time is required between each coat. Leave enough room in your schedule to compensate. Also take into consideration the paints pot life. Finally, dont forget to watch the weather to monitor any drastic changes in temperature, humidity, and wind, etc. The more you plan the more control youll have and the better the paint job will be.
