Product Information
Full details
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.

FAQs
Can I use C4 on interior plastic trim?
No, C4 is specifically engineered for exterior plastic and rubber components exposed to UV and weather.
How long does the protection last?
When applied to a correctly prepared surface, it can last up to two years.
Do I need to remove old trim dressings first?
Yes, removing old dressings with a solvent or panel wipe is mandatory for the product to bond correctly.
Is C4 suitable for textured plastic?
Yes, it works exceptionally well on textured plastic and helps restore the factory-black look.
Can I layer the product for more protection?
C4 is designed as a single-layer application. Adding multiple layers does not improve performance.
What if it rains shortly after application?
The coating requires 12 hours to cure. If it rains within this period, the bond may be compromised, leading to spots or premature failure.
Troubleshooting
Streaking or uneven finish
Usually caused by applying too much product; buff immediately with a clean microfibre cloth to level the coating.
Product won't stick/lasts only a few weeks
The surface was likely not cleaned properly. Use a strong panel wipe or alcohol-based cleaner to remove all old silicones before reapplying.
Accidental application on paintwork
Wipe off immediately with a clean, dry microfibre cloth before the product bonds to the clear coat.
Pros and Cons
Pros
- Significantly longer lifespan than standard dressings
- Does not wash off after a single rain shower
- Non-greasy, natural factory finish
- Highly concentrated formula
- Provides real UV defense for aging plastic
Cons
- Requires extremely clean, residue-free surfaces
- Small bottle size can be difficult to handle
- Requires a steady hand to avoid getting product on paint
- Long cure time before exposure to moisture
Setup, Compatibility & Care
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.
- Ensure the trim is cool and completely dry.
- Clean the surface with a degreaser or IPA.
- Apply the product in a dust-free environment.
- Allow at least 12 hours of dry time before exposing the treated surfaces to rain or water.
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.
