This is one of the most common questions we get, and it depends on the condition of the trim.

For lightly faded plastics, a quality black trim restorer or trim coating, such as CARPRO Perl, will usually restore some colour in one application. For heavily faded or uneven trim, you may need a dedicated restoration product, such as Solution Finish Trim Restorer, with stronger bonding properties, sometimes even multiple applications.

If the plastic is physically damaged or turning white from deep oxidation, no product will completely fix that. In those cases, restoration improves it significantly, but it may not return to factory-new.

Proper cleaning beforehand makes a bigger difference than most people realise.

Longevity varies depending on the product type, prep and how often the vehicle is used.

Basic dressings may last a few weeks. A proper car trim restorer or trim coating can last months. sometimes longer if maintained correctly.

Factors that can affect durability:

• UV exposure
• Car maintenance
• Use of harsh chemicals
• Condition of trim

In most cases, yes. Plastic trim restorer are designed for textured black or grey exterior plastics such as bumpers, mirror surrounds, cowl panels, door and window rubbers etc.

However, you should avoid using them on:

• Painted surfaces
• Clear plastics such as headlights
• Windscreen wiper blades
