Exposure to harmful UV rays, road grime, and routine car washes can dull your plastic trim, leaving it gray, faded, and brittle. That’s where C4 Permanent Trim Restorer steps in. Engineered with our advanced smart surface science, this trim restorer bonds to your vehicle’s exterior plastic surfaces at a molecular level—offering results that look better and last longer.

Unlike a typical trim dressing or black plastic restorer that leaves behind a greasy residue, C4 provides a natural finish with no oily buildup. Whether you’re restoring your rear bumper, door handles, or any vinyl surface, C4 works across a wide range of plastic surfaces, including textured rubber and exterior car trim. It’s the go-to product for any professional detailer or car enthusiast who wants long-term performance without constant reapplication.
