Gtechniq C4 Permanent Trim Restorer
Bring your faded trim back to life – for the long haul
What is C4 Trim Restorer?
If your car’s plastic trim has gone dull, grey and chalky from UV exposure, road grime or constant washes, C4 is the solution. This isn’t just a “dress up” job. Gtechniq’s C4 forms a chemical bond with your exterior trim (plastic, vinyl, rubber) – becoming part of the surface, not just sitting on top. The result? Trim that looks “as new” again and stays like that.
Key Features & Benefits
| Benefit | Why It Matters |
|---|---|
| Long-lasting protection (up to 2 years) | You’ll spend less time redoing your trim; fewer re-applications. |
| Natural finish, no grease or shine | Keeps the original texture; avoids slippery or overly glossy trim that attracts dirt. |
| Works on most exterior trim types | Door handles, bumpers, textured plastics & rubber, etc. |
| Durable chemistry | The coating “swaps part of its molecular structure” with the plastic – that gives C4 its lasting performance. |
How to Use / Application Guide
To get the best results out of C4, follow these steps:
-
Prep properly
Clean the trim thoroughly—remove old dressings, grime or oils. If needed, use a citrus-based all-purpose cleaner and scrub with a medium stiff brush. The surface must be dry and contaminant-free. -
Ideal conditions
Apply when temperature is above ~5 °C, on a cool surface, and out of direct sunlight. Ventilate if indoors. Wear gloves. -
Application
Use a lint-free applicator pad; dampen it with a few drops of C4 and spread evenly over the trim. For very textured trim, take your time to get into the crevices. -
Remove excess
Immediately after applying a section, buff off any residue using a quality microfibre cloth. If residue is left in deep textures, it may turn powdery. -
Cure time
Allow around 12 hours for the coating to cure before exposing to water or harsh conditions. -
Storage & usage tips
-
Use within three months after opening.
-
Store in a cool, dry place away from direct sunlight.
-
Choose the right size: a small car or trim set needs less product; large areas (bumpers, side skirts) need more.
-
Why Choose This Over Other Trim Dressings
-
Most trim dressings wash off quickly or leave oily, unnatural surfaces. C4 gives a natural, semi-matte finish that resists fading and doesn’t attract dirt.
-
It’s built for durability: you should get up to two years’ protection with a single application.
-
Because it forms a chemical / molecular bond, it outperforms typical “spray on, dressings” in both finish and longevity.
