Gtechniq C4 Permanent Trim Restorer 1 fl oz — nano‑bond trim coating, UV & water resistant

Gtechniq C4 Permanent Trim Restorer is a nano‑bonding trim coating that permanently revives and protects faded exterior plastic and rubber surfaces with an ultra‑thin, durable finish.

Designed for automotive enthusiasts and professionals, this concentrated 1 fl oz formula chemically bonds with trim substrates to restore colour and texture while delivering long‑term resistance to UV and moisture. Unlike temporary dressings that sit on the surface, C4 integrates with the plastic at a molecular level to produce a resilient, natural-looking finish that resists wash-off and staining.

How does Gtechniq C4 restore faded trim?

C4 works by forming a molecular bond with plastic and rubber surfaces, replacing part of the material's surface layer with an engineered coating. This process restores original colour saturation and reduces the chalky, weathered look without leaving a glossy, artificial sheen.

• Molecular-level bond restores colour and texture rather than masking defects
• Invisible, thin coating maintains factory matte or satin appearance
• Works on bumpers, mirror housings, side moldings and rubber seals

How long does the protection last and what does it resist?

The bonded coating offers durable protection against sunlight and water, significantly slowing re-fading compared with topical dressings. Longevity depends on exposure and maintenance, but the chemical bond provides much stronger resistance to wash-off and environmental attack than traditional products.

• Improved UV resistance reduces re-fading from sunlight
• Hydrophobic surface sheds water and grime more effectively
• Not designed to be a sacrificial film — it becomes part of the substrate

How do I apply C4 and how much will I need?

Application is straightforward: clean the surface thoroughly, apply a small amount evenly, allow bonding time, then remove any excess. The 1 fl oz bottle is concentrated, so a little covers multiple trim pieces; a single car exterior typically requires only small doses for bumpers, mirrors and door trims.

• Surface must be clean, dry and free of previous dressings
• Use an applicator pad for even coverage and minimal product waste
• Allow recommended cure time before exposure to rain or heavy washing

Is C4 safe for different plastics and finishes?

C4 is formulated to chemically bond with most automotive plastics and rubber without altering texture or creating an overly glossy look. It was developed using advanced nanotechnology to provide strong adhesion while preserving the OEM appearance; compatibility checks on small areas are recommended for mixed or delicate surfaces.

• Suitable for most exterior trim, bumpers and rubber seals
• Maintains original matte or satin finish rather than high gloss
• Test small, inconspicuous areas when unsure of substrate type

Who is this for: Gtechniq C4 is aimed at car owners, detailers and restoration enthusiasts who want a long‑lasting, natural-looking solution for tired or sun-damaged trim. If you prefer bonded, paint‑like durability over temporary dressings and value a discreet finish that revitalises colour without shine, C4 is built for your needs.
