Clear polycarbonate plastic roof panels can be painted, but it requires proper preparation for the paint to adhere well. Since the surface is smooth and non-porous, lightly sanding it helps create grip. Use a primer specifically designed for plastics before applying any paint. Acrylic or spray paints made for plastic surfaces work best. Avoid oil-based paints as they may not stick properly and could peel over time. Make sure the panels are clean and dry before starting. Painting can reduce the transparency of the panels, so consider if that fits your needs. Always follow safety and manufacturer guidelines when painting polycarbonate.
