C4 Permanent Trim Restorer - Case

C4 Permanent Trim Restorer forms a true chemical bond with plastic trim, becoming an integral part of the surface rather than merely sitting on top. Unlike weaker electrostatic bonds found in many PTFE-based products, C4 covalently bonds with the plastic, effectively exchanging part of its molecular structure with that of the trim. The result? A highly durable, ultra-thin (~30nm), optically clear protective coating that doesn’t leave behind a greasy or overly glossy finish. Instead, it restores and rejuvenates faded trim, bringing it back to an “as-new” appearance without altering the natural texture or look of the material. Thanks to its advanced formulation and deep bonding capability, C4 offers up to 2 years of protection from a single application—far outperforming conventional trim dressings in both longevity and finish quality.
