Faded black trim transforms a sharp car into a neglected one within years. Road & Track tested leading trim restorers to identify which products genuinely revive weathered plastic instead of delivering temporary fixes.
Exterior trim degrades fast. UV exposure breaks down the polymer coating on bumpers, window moldings, and door handles, leaving a chalky white haze that screams deferred maintenance. Most owners recognize the problem but struggle to find solutions that last beyond a few weeks.
The publication evaluated popular products across real-world conditions. Testing focused on durability, ease of application, and how long the darkening effect persists. Some restorers merely coat the surface with glossy finishes that wash away in the first rain. Others penetrate the plastic itself, rebuilding the protective layer that UV rays destroyed.
Application matters. Spray products offer convenience but often deliver uneven coverage and pool in crevices. Liquid formulas with applicator pads give users control but demand patience and proper technique. Wipe-on solutions fall somewhere between, balancing speed with precision.
The best performers typically combine a penetrating restorer with a durable topcoat. These two-step approaches cost more upfront but justify the expense through longevity. Single-product solutions rarely match this performance.
Trim restoration remains largely unchanged from five years ago. Chemical technology improves slowly in this category because the underlying problem—plastic degradation—resists quick fixes. Many owners accept that restorers require annual or biannual reapplication as part of vehicle maintenance.
For buyers tired of chalky trim, Road & Track's testing narrows the field to proven options. The difference between a great restorer and a mediocre one often means the gap between six months of results and eighteen months.
