While most of those words are used as marketing buzzwords in the current day, true ceramic coatings, sometimes infused with graphene to aid with water spot resistance, are meant to be a 'sacrificial' layer on top of your paint and clearcoat to protect it. True ceramic coatings protect your car from ultraviolet light, chemical damage, minor scratching, and more. True ceramic coatings also offer a much more sleek and shiny look to your car's paint and glass, providing unparalleled ease of cleaning, hydrophobicity, and rain visibility if applied on the windshield.
