How do I repaint batting helmet?

To repaint a batting helmet, first clean it thoroughly with soap and water to remove dirt and oils. Lightly sand the surface to help the new paint adhere, then apply a primer designed for plastic or fiberglass. Once the primer dries, use spray paint suitable for plastics to apply an even coat, allowing adequate drying time between layers. Finish with a clear coat for protection and shine, ensuring everything is fully dry before use.
