Understanding the Damage

Before you start, assess the extent of the damage. Is it a minor scratch, a deep crack, or a missing piece? The repair method you choose will depend on the severity of the damage. For minor scratches and scuffs, a simple cleaning and polishing might suffice. Deeper cracks might require plastic welding or fillers. Missing pieces might necessitate replacement or more advanced repair techniques.

Gathering Your Supplies

Having the right tools and materials is crucial for a successful repair. Depending on the chosen method, you might need:

Cleaning solution (car wash soap, degreaser)
Sandpaper (various grits)
Plastic filler (epoxy or specialized plastic repair putty)
Plastic welding kit (if applicable)
Primer
Paint (matched to your car’s color)
Clear coat
Masking tape and paper
Heat gun or hair dryer
Gloves and safety glasses

Repairing Minor Scratches and Scuffs

For light scratches and scuffs, start by thoroughly cleaning the affected area with car wash soap and water. Dry the area completely. Next, use a fine-grit sandpaper (e.g., 2000-grit) to gently buff out the imperfections. Follow up with a rubbing compound and polish to restore the shine.

Repairing Cracks with Plastic Filler

Deeper cracks require a more involved approach. Clean the area thoroughly and sand the cracked edges with progressively coarser sandpaper (e.g., 180-grit to 320-grit). Apply a plastic filler according to the manufacturer’s instructions, ensuring complete coverage of the crack. Allow the filler to dry and cure completely. Then, sand the repaired area smooth using progressively finer sandpaper until it blends seamlessly with the surrounding molding.

Plastic Welding: A More Permanent Solution

Plastic welding offers a more permanent fix for severe cracks and broken pieces. A plastic welding kit melts plastic rods to fuse the broken pieces together. This method requires practice and precision, but it provides a strong and durable repair. Ensure you choose the correct type of plastic welding rod that matches your car’s molding material.

Priming and Painting for a Flawless Finish

After the repair is complete, prime the repaired area to promote paint adhesion. Apply several thin coats of primer, allowing each coat to dry before applying the next. Once the primer is dry, apply thin coats of automotive paint that matches your car’s color. Finish with a clear coat to protect the paint and add shine.

How to Prevent Future Damage

Regular cleaning and waxing can protect your car’s plastic molding from UV damage and prevent minor scratches. Avoid parking too close to other vehicles or objects that could scrape against your car. Consider applying a protective film or coating to vulnerable areas.
