CeraTrim is a ceramic based trim restorer" CeraTrim uses our popular and effective ceramic technology to bond deep into the pores of plastic trim surfaces, removing the impurities that have built up in the plastic and effectively restoring them to their original appearance. Unlike most trim products, CeraTrim is no mere dressing or stain. It is a true ceramic coating that will give your trim surfaces superior hydrophobic and self-cleaning properties and will protect your trim for the long haul under any driving conditions while restoring them to a newer appearance. CeraTrim can be used on all trim pieces throughout your vehicle, inside and out. It can be used on engine bay plastics to restore their appearance.
