Before painting any plastic surface, it is important to sand it first. This will create a smooth surface for the paint to adhere to and will help to prevent any brushstrokes from showing through the final paint job.
When sanding plastic, it is important to use a very fine grit sandpaper. A grit of 400 or higher will work well. Be sure to sand in the direction of the grain and to avoid sanding too deeply into the plastic.
Once the sanding is complete, wipe away any dust with a clean cloth. Then, you are ready to begin painting.
