Preparation is critical for a strong bond between the paint and any plastic or waterproof panel. Clean the panels thoroughly with a grease-fighting soap and sand them with fine-grit sandpaper. After that, wipe the panels down with an acetone solution to remove any dust or grease. Wipe the surface immediately with a clean, damp cloth to remove any remaining acetone. Any remaining acetone on the plastic will cause adhesion issues. If this step is skipped, the paint will not adhere to the plastic.
