Ranked picks
- Garage Therapy Tartarus Trim Coating — a high-solids inorganic ceramic coating that bonds to and penetrates hard plastic trim, deepening faded trim with a satin restoration and shielding it from UV, acid rain, road salt and bird droppings for up to about 3 years. Supplied as a kit with applicator block and suedes. The new longevity leader here.
- 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 established 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.
- Turtle Wax Hybrid Solutions Graphene Acrylic Trim Restorer — a graphene-and-acrylic coating that blackens dull, faded textured plastic with added UV protection, dries to the touch in minutes and resists wash-off through seasons. The accessible, easy-to-use step up from a dye toward coating durability.
- 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.
- 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 — ceramic (Garage Therapy Tartarus ~3 years, Carbon Collective Platinum ~2 years), molecular-bonding (Gtechniq C4 ~2 years), graphene (Turtle Wax) — last longest but demand clean, dry, fully prepped trim and careful application. Dye-based restorers and dressings (Adam's, Sonax) are faster and cheaper but need re-applying every few months. For severely greyed trim, a tinting paint like Sonax restores deepest. To avoid staining adjacent paint or a greasy look, choose a dye-free or oil-free formula (McKee's SiO2, Gtechniq C4). If you specifically want a wet, glossy black rather than a factory-matte finish, use a gloss trim gel or dressing instead of a coating. 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 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. Ceramic and bonding coatings such as Garage Therapy Tartarus (up to ~3 years) and Gtechniq C4 (~2 years) far outlast dressings and dye treatments, which typically last weeks to a few months and need topping up.
