Can I Put a Mechanics Lien on a Roofing Company? Yes, clear polycarbonate plastic roof panels can be painted, but it requires special care. First, clean the surface thoroughly to remove dirt and oils. Use a plastic-compatible primer to ensure proper adhesion of the paint. Choose a paint that is designed for use on plastic or polycarbonate surfaces, such as acrylic or spray paint specifically for plastics. It’s important to select a paint that won’t block the light transmission or degrade the material. Light coats are recommended to avoid streaking or uneven coverage. Be sure to allow proper drying time between coats. Painting can provide a new look and additional UV protection for the panels.
