Gtechniq C4 Permanent Trim Restorer is designed for car enthusiasts and detailers who want to restore faded exterior plastic and rubber trim to a like-new state. Its primary benefit is a chemically bonded, long-lasting protective layer that resists UV damage and rain far longer than traditional surface dressings. While highly effective, the product requires meticulous surface preparation, as any oils or existing contaminants will prevent the chemical bond, potentially leading to uneven results.

No, C4 is specifically engineered for exterior plastic and rubber components exposed to UV and weather.
When applied to a correctly prepared surface, it can last up to two years.
Yes, removing old dressings with a solvent or panel wipe is mandatory for the product to bond correctly.
Yes, it works exceptionally well on textured plastic and helps restore the factory-black look.
C4 is designed as a single-layer application. Adding multiple layers does not improve performance.
The coating requires 12 hours to cure. If it rains within this period, the bond may be compromised, leading to spots or premature failure.
Usually caused by applying too much product; buff immediately with a clean microfibre cloth to level the coating.
The surface was likely not cleaned properly. Use a strong panel wipe or alcohol-based cleaner to remove all old silicones before reapplying.
Wipe off immediately with a clean, dry microfibre cloth before the product bonds to the clear coat.
Before application, the trim must be thoroughly cleaned and stripped of all previous dressings, waxes, or oils. Using a dedicated panel wipe or isopropyl alcohol (IPA) is critical to ensure the trim surface is chemically clean.
Store the bottle in a cool, dark place away from direct sunlight, and ensure the cap is tightened firmly to prevent the product from curing inside the bottle.
