How To Paint Plastic Car Interior Trim

Plastic interior trim is a common feature in many cars. It can be found on the dashboard, door panels, and center console. While plastic trim can be durable, it can also become scratched or faded over time. If you're looking to refresh the look of your car's interior, painting the plastic trim is a relatively easy and inexpensive way to do so. Here are the steps on how to paint plastic car interior trim:

Materials You'll Need:

Sandpaper (120-grit, 220-grit)
Adhesion promoter
Primer
Automotive paint
Clear coat
Masking tape
Tack cloths

Step 1: Preparation

The first step is to prepare the plastic trim for painting. This involves cleaning the surface with a mild detergent and water, then sanding it with 120-grit sandpaper to remove any scratches or imperfections. Once the surface is sanded, wipe it down with a tack cloth to remove any dust.

Step 2: Apply Adhesion Promoter

Adhesion promoter is a chemical that helps the paint to stick to the plastic. Apply a thin coat of adhesion promoter to the surface of the trim, then allow it to dry completely.

Step 3: Apply Primer

Primer is a base coat that helps the paint to adhere to the plastic. Apply a thin coat of primer to the surface of the trim, then allow it to dry completely.

Step 4: Apply Paint

Once the primer is dry, you can begin applying the paint. Use even strokes and apply several thin coats, allowing each coat to dry completely before applying the next. It's important to use automotive paint specifically designed for plastic surfaces.

Step 5: Apply Clear Coat

Once the paint is dry, you can apply a clear coat to protect it. Clear coat also gives the paint a glossy finish. Apply several thin coats of clear coat, allowing each coat to dry completely before applying the next.

Step 6: Reinstall Trim

Once the clear coat is dry, you can reinstall the trim in your car. Be sure to allow the paint and clear coat to cure for a few days before exposing the trim to excessive heat or moisture.

Tips:

Use a light touch when sanding the plastic trim. Sanding too aggressively can damage the surface.
Allow each coat of paint or clear coat to dry completely before applying the next. This will help to prevent the paint from peeling or chipping.
Use masking tape to protect any areas of the trim that you don't want to paint.
If you're not sure about any of the steps involved in painting plastic car interior trim, it's always best to consult with a professional.
