Permanent Trim Science
Restore faded trim that actually stays restored
C4 does not sit on top of the plastic - it bonds to the surface at a molecular level, which is why the results last up to 2 years instead of washing off after a few rains. UV rays and road grime are the main culprits behind grey, brittle trim, and C4 is built specifically to reverse that damage and keep it from coming back.
Why C4
Built to last, not to reapply
Four reasons professional detailers reach for C4 on trim work.
-
Molecular-Level Bond
C4 chemically bonds to plastic and rubber so it cannot be washed or wiped away.
-
UV and Fade Protection
Shields exterior trim from UV degradation that turns plastic grey and brittle over time.
-
Natural, Grease-Free Finish
Cures to a clean, factory-style look with no oily film, dust attraction, or fling-off.
-
Up to 2 Years Durability
One thorough application protects and restores trim for up to two years of normal use.
C4 vs. Typical Trim Dressings
Not all trim products are equal
Most trim dressings do a cosmetic job - they darken the plastic and look good for a week. C4 is a coating, not a dressing, and the difference shows up every time it rains.
| Feature | DetailerSA | Alternative |
|---|---|---|
| Bonds chemically to plastic surface | Yes | No |
| Up to 2 years durability | Yes | No |
| Natural, non-greasy finish | Yes | No |
| Works on textured rubber and vinyl | Yes | Yes |
| Darkens and restores faded trim colour | Yes | Yes |
| Requires no periodic reapplication | Yes | No |
The Finish That Matters
Natural look, zero grease
Unlike trim dressings that leave a slick, oily layer that attracts dust and flings off under a pressure washer, C4 cures to a clean, natural finish that looks like factory plastic - not dressed plastic. It suits every exterior trim type, from smooth door handles to aggressively textured rear bumpers.

Questions
Frequently asked
What surfaces can I use C4 on?
C4 is designed for all exterior plastic trim, including textured rubber, vinyl, door handles, mirror housings, and bumpers. It is not intended for painted surfaces, glass, or wheels - stick to unpainted exterior plastic and rubber components.
How do I prepare the trim before applying C4?
The surface must be completely free of contaminants before application. Clean the trim thoroughly with a neat all-purpose cleaner (APC), and use a medium-stiff brush on heavily textured areas. Any wax, dressing, or silicone residue left on the trim will compromise adhesion, so don't skip this step.
What is the application process?
Work in a well-ventilated area above 5°C on a cool surface, out of direct sunlight. Wear the gloves provided. Soak the included AP1 applicator with several drops of C4 and spread it evenly across the trim. Work section by section so you don't miss any areas before the product starts to flash.
How long does C4 take to cure, and when can the car get wet?
Allow C4 to cure fully before the vehicle is exposed to rain or washing. Gtechniq recommends keeping the treated surfaces dry during the initial cure period - check the product label for the exact cure window, as ambient temperature affects how quickly the coating sets.
How long does C4 last?
C4 offers up to 2 years of durability on exterior trim under normal driving and washing conditions. Longevity depends on how well the surface was prepared before application and how frequently the vehicle is washed.
How much product do I need?
Coverage varies by vehicle size. As a general guide, a small sedan requires around 15ml and a larger SUV around 30ml. Make sure you have enough product to treat all trim in one session - running out mid-job can leave uneven results.
Can C4 be layered with other coatings or topped with a trim dressing?
C4 is a standalone coating engineered to bond directly to plastic and rubber. Applying a silicone-based dressing or another coating on top can interfere with its bond and compromise durability. For best results, use C4 on its own over a properly prepared surface.
What finish does C4 leave, and will it look shiny or greasy?
C4 is formulated to restore a natural, factory-style finish rather than a high-gloss or wet-look sheen. There is no oily film or greasy residue - the trim simply looks restored and even, the way it looked when the vehicle was new.
