Before Essence Plus, a damaged ceramic coating usually meant polishing it off and starting again, as CarPro US points out. Essence Plus builds up and levels the existing coating instead, adding gloss and SiO2 protection.
Treat it as a repair and refresh for a coated car, not a correction. Deeper defects still need polishing, while fine swirls and dull areas are where it helps.
CarPro US adds that it cleanses as it glosses, leaving a smooth-as-glass feel, and that water beads up instantly and glides off, carrying dust and grime with it.
