Why Does My Car’s Plastic Trim Keep Fading? (And How to Stop It)
Ever notice your trim looks great after a detail—but just weeks later it’s back to being chalky and gray? You’re not alone. Faded plastic trim is one of the most frustrating parts of exterior maintenance, and it’s often caused by a few overlooked factors.
In this post, we’ll break down the real reasons your plastic trim keeps fading—and how to keep it black and protected using a product like Jimbo’s All Dressed Up.
What Causes Plastic Trim to Fade?
1. UV Exposure
The sun’s ultraviolet rays break down the surface of uncoated plastic over time, causing it to dry out and fade. This is the #1 reason for dull, grayed-out trim—especially in hot climates or cars parked outside regularly.
2. Harsh Chemicals and Detergents
Household cleaners, engine degreasers, or heavy-duty car soaps can strip natural oils and protective finishes from your trim—leaving it brittle and prone to discoloration.
3. Neglect or Infrequent Maintenance
Trim, like paint, needs regular cleaning and protection. Without it, plastic starts to oxidize, absorb contaminants, and degrade faster with each wash cycle or exposure to the elements.
Why Most Trim Restorers Don’t Last
Many trim dressings look great for a day or two, then streak, fade, or wash off in the rain. That’s because they’re often silicone-based or overly greasy—designed for quick shine, not long-term durability.
How to Keep Your Trim from Fading
Step 1: Clean the Trim Thoroughly
Use a gentle soap like The Super Soaper or an APC to remove dirt, old product, and oxidation. Rinse and let dry completely.
Step 2: Apply a Water-Based Trim Dressing
All Dressed Up penetrates the surface and nourishes the plastic without being oily or shiny. It restores a rich black finish and leaves behind protection that lasts.
- ✅ OEM-style matte finish
- ✅ Water-based and non-greasy
- ✅ Can be used straight or diluted 4:1
- ✅ Safe on trim, tires, and engine plastics
Step 3: Maintain Every Few Weeks
Reapply every 3–6 weeks (or after a few washes) to keep your trim dark, conditioned, and UV-protected. You can even use it as a drying aid on trim after a wash.
