Faded plastic trim makes even a clean, polished car look older than it is. UV rays, road salt, chemicals, and age can turn black plastic gray and dull, especially on bumpers, mirrors, wheel arches, and vents.
The good news? You can restore that deep black finish quickly and permanently with the right surface prep and professional-grade products. Whether you’re a DIYer or a detailing pro, this guide walks you through a step-by-step restoration process that delivers long-lasting results — and adds serious value to your services.
Step-by-Step: How to Restore Plastic Trim
Step 1: Inspect the Vehicle
Many customers may not realize you offer plastic trim restoration, so mentioning it during your vehicle inspection is essential. As you inspect a car, pay attention to these commonly affected areas:
- Door handles
- Front and back bumpers
- Door moldings
- Mirrors
- Roof racks
- Running boards
- Bed liners
- Mud flaps
- Windshield Cowls
If you notice faded or worn-out plastic trim, explain to your customer that restoring automotive plastic enhances the vehicle’s appearance and can even boost the resale value or minimize lease return fees. Highlighting these benefits makes fixing faded plastic trim a simple and lucrative upsell.
Step 2: Clean & Prep the Surface
Before applying any plastic trim restorer, make sure the surface is clean and bare:
- Use an alcohol-based prep solution like Wipe Clean Surface Prep to remove dirt, wax, dressings, and any oily residue.
- If the trim was previously dressed or coated, scrub with a soft detailing brush and rinse before wiping again with Wipe Clean.
This ensures maximum adhesion and a more even finish.
Step 3: Mask Off Surrounding Areas
Use safe-release painter’s tape to protect paint and glass around the trim:
- Tape off tight edges and seams to avoid accidental staining or overspread during application.
- This step is especially important on panels with tight body lines or multiple finishes.
Step 4: Apply the Trim Restorer
To restore the deep black appearance, apply a semi-permanent dye like Trim Kote Car Trim Restorer:
- Wear nitrile gloves to protect your hands.
- Apply Black Trim Kote to a clean towel, sponge, or applicator pad.
- Rub the product evenly into the plastic in small sections (about 4″ x 6″).
- Avoid over-saturating the surface — a little goes a long way.
- Allow each section to dry fully before layering or moving to the next area.
Pro tip: In warm weather, Trim Kote dries in 5–10 minutes. In cooler temps, drying may take 15–20 minutes. Avoid applying in direct sunlight or during high humidity to ensure even coverage.
Step 4: Protect the Restored Trim
Once the color has been restored, seal it with a UV-protective dressing:
- Use Revival Bumper & Trim Dressing to condition and protect the trim from fading, oxidation, and future environmental damage.
- Apply evenly with a clean foam or microfiber applicator.
- Buff for a uniform finish with no streaks or residue.
This topcoat step enhances appearance and provides critical UV resistance.
