Faded Exterior Plastics? Here’s How to Restore and Protect Them from Sun Damage

Published on June 9th, 2025

Over time, exposure to sun, rain, and harsh weather conditions can cause once-deep black exterior plastics to fade, turning them dull and chalky gray. This affects parts like side mirrors, bumpers, trims, and moldings, which not only diminishes your vehicle’s appearance but can also contribute to long-term deterioration.

The good news is that you can restore faded plastics and protect them from future sun damage by using the right methods and products.

Why Do Exterior Plastics Turn White or Gray?

The answer is UV exposure. Plastic parts on your car contain oils and color pigments that degrade over time when exposed to sunlight. As these oils evaporate, the plastic dries out and oxidizes, leading to:

  • A chalky white or gray appearance
  • A brittle texture
  • Loss of flexibility and strength

This is especially common in hot climates or on vehicles frequently parked outdoors.

How to Restore Faded Exterior Plastics (Step-by-Step)

Here’s how to get that deep, rich black finish back — safely and effectively.

1. Clean the Surface Thoroughly

Before applying any product, make sure the plastic is free of dirt, grease, or old dressings.

  • Use a plastic-safe cleaner or APC (all-purpose cleaner)
  • Scrub gently with a soft brush or sponge
  • Rinse and dry completely

Pro tip: Cleaning well ensures the product adheres better and lasts longer.

2. Use a High-Quality Plastic Restorer or Trim Dressing

Choose a product specifically made for exterior trim restoration. Look for:

  • UV protection
  • Water resistance
  • Long-lasting finish
  • No oily or greasy residue

Apply using a foam applicator or microfiber pad. Spread evenly across the surface, and let it penetrate.

3. Remove Excess Product

After letting the product sit for a few minutes (check label instructions), buff off any residue with a clean microfiber towel. This helps even out the finish and prevents streaks.

4. Layer for Better Results (Optional)

For heavily oxidized plastics, a second or third layer may be necessary. Just wait for the first layer to cure before applying again.

How to Protect Plastics from Sun Damage

Once your plastics are restored, keep them looking good with a few simple habits:

  • Apply a trim protectant regularly (every 4–6 weeks, or as needed)
  • Park in shaded areas or garages when possible
  • Use a car cover for long periods of outdoor storage
  • Wash and maintain trims during your regular detailing routine

What NOT to Use

  • Household oils (like olive or baby oil) – they attract dust and fade quickly
  • Tire shines on plastic – may cause staining or streaking
  • Heat guns or DIY flame tricks – they can permanently damage the plastic

Final Thoughts

Faded plastics don’t have to be permanent. With the right cleaning, restoration, and UV protection, your car’s exterior trim can go from tired and chalky to sleek and showroom-worthy — in just minutes.

Don’t let the sun win. Revitalize, protect, and enjoy a bold, clean look — all year round.
