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.
How to use C4:
Make sure before you start you have enough product for all of your trim. For example, if you have a SUV (30ml) you would need more product than you would on a small sedan (15ml)
Work in a well-ventilated area, at a temperature above 5ºC (41ºF) on a cool surface out of direct sunlight. Wear the gloves provided.
Ensure the surface(s) you are going to coat are free from any contaminants. For best results clean trim with a neat solution (APC), and if required use a medium stiff brush
Use the applicator supplied to spread the coating onto the surface of your trim. Soak the pad with several drops of product
Once you have spread the product over each piece of trim, gently wipe away residue immediately with a buffing cloth. If your car has heavily textured trim take time to ensure all crevices are covered, and that all residue is also removed from them
Allow the coating to cure for 12 hours before exposing to the elements
Use within 3 months of opening
Store in a cool, dry place
