Can clear Polycarbonate Plastic Roof Panels be Painted? It is possible to paint roof panels made of clear polycarbonate plastic! A smooth and long-lasting finish is guaranteed when water-based acrylic paint is used. Cleaning and mild sanding are examples of proper surface preparation that improves paint adhesion. Durability can be increased by using a primer made for plastics. For an even layer, use a high-quality brush or a spray gun. A single thick coat is less effective than several small coatings. Before adding the next coat, let the previous one completely dry. You can get a polished and fashionable finish using the correct methods!
