How to Paint a Plastic Interior
- 1). Clean the plastic with a mixture of water and dish detergent. Use the rough end of a sponge to thoroughly clean the surface of the plastic interior.
- 2). Dry the plastic interior with a clean cloth.
- 3). Lightly sand the surface of the plastic interior with 600 grit sandpaper. Sand the plastic until it is no longer glossy. Wipe away the sanding dust with a damp cloth or sponge.
- 4). Coat the plastic with a thin coat of plastic primer. Let the primer dry completely.
- 5). Apply three coats of paint specifically designed for plastic. Allow the paint to dry until it is slightly tacky between coats. Let the last coat of paint dry for 24 to 48 hours before use.
