How To Paint Auto Plastic Parts

There’s nothing better looking than a freshly painted, well maintained vehicle. Unfortunately, once a vehicle leaves the showroom, its appearance eventually succumbs to the wear and tear of the weather, sand, gravel, and other paint-damaging debris. The elements slowly cause a vehicle’s plastic trim to look worn.

When painting plastic auto parts, different preparation and products are required than painting a vehicles sheet metal.

Plastic auto parts include trim pieces, door handles, mirror housing and various other trims. Touching up small areas on your vehicle’s paintwork can make a huge difference to the overall appearance and value of the vehicle.

Paint plastic auto parts correctly, and your paint job will last for years…


WHAT YOU WILL NEED:

Always wear a face mask when sanding or spraying primer and paint - Options here


STEP 1 If possible, remove the plastic parts from the vehicle. This allows for more thorough cleaning and preparation. If parts cannot be removed, mask the area surrounding it.

STEP 2 Wash the plastic auto parts with car wash detergent and rinse clean with water. Allow to completely dry, then wipe the plastic with rubbing alcohol. Use a clean, lint-free towel to wipe the plastic with wax and grease remover.

STEP 3 Sand the plastic trip with 800 grit sandpaper and water. Keep the sandpaper soaking wet whilst sanding to stop dust from building up under the paper and scratching the surface. Rinse and allow to dry.

STEP 4 Apply an adhesion promoter to the plastic trip so that the primer and paint will stick to it. Apply the adhesion promoter just as you would a coat of paint – using light, event coats. Allow to dry. Prime with two thin coats of primer, allowing each coat to dry.

STEP 5 Paint the plastic auto part with three coats of paint, allowing each coat to dry completely. Spray two coats of clear on the part and allow to dry overnight.


For a superior high-gloss result, you can use a cut and polish for desired effect.
