Ranked picks
- Gtechniq C4 Permanent Trim Restorer — bonds at the molecular level to plastic, vinyl and textured rubber for up to ~2 years; leaves a dry, oil-free natural look rather than a greasy shine. The benchmark for permanence.
- Carbon Collective Platinum Trim Ceramic Coating — a true ceramic coating with a 3H hardness barrier rated ~2 years, giving an OEM-grade satin finish plus UV and chemical resistance.
- GYEON Q² Trim EVO — restores colour and slows future UV fade while staying deep and clean without an artificial gloss; good for protecting newer trim too.
- Sonax Plastic Restorer black — a water-based, silicone-free tinting paint for severely faded, grey trim; the built-in sponge applicator keeps the strongest restoration clean and controlled.
- McKee's 37 SiO2 Plastic Trim Restorer — clear and dye-free, so it darkens trim without staining surrounding paint; water-resistant through repeated washes with UVA/UVB absorbers.
- Chemical Guys Rapid Black Trim & Plastic Restorer — a light suspension-gel that delivers a deep, glossy black; pick this if you prefer a wet shine over a factory-matte look.
- Adam's Black Trim Restorer — a simple wipe-on-and-dry dye that revives colour for several months; the easiest, most affordable starting point.
How to choose
Match durability to effort: coatings (Gtechniq C4, Carbon Collective, GYEON) last up to ~2 years but demand clean, dry, fully prepped trim and careful application; dye-based restorers and dressings (Adam's, Sonax, Chemical Guys) are faster and cheaper but need re-applying every few months. For severely greyed trim, a tinting paint like Sonax restores deepest. If you want to avoid staining adjacent paint or want a non-greasy look, choose a dye-free or oil-free formula (McKee's SiO2, Gtechniq C4). Always decontaminate and dry the trim first — any wax, dressing or grease left behind wrecks adhesion and durability.
FAQ
How do I prep trim before a restorer or coating?
Clean the trim with an all-purpose cleaner or panel wipe to strip old dressing, wax and grease, then dry fully. Coatings especially will not bond to a contaminated or damp surface.
Why does my trim turn white or chalky after some products?
White residue is usually product (or a sealant like a coating's carrier) drying in the textured grain, not damage. Work it in thin, wipe excess before it flashes, and use a dye-free restorer on porous trim to avoid streaks.
Do trim coatings last longer than dressings?
Yes. Bonding coatings such as Gtechniq C4 and Carbon Collective Platinum are rated up to ~2 years, while dressings and dye treatments typically last weeks to a few months and need topping up.
