Both liquid polymers are under the same classification of a nanotechnology based paint protection. They look very similar in appearance, stored the same way, but will vary in their performance and composition (Silicon Dioxide Vs Graphene Oxide). Ceramic coatings are still a popular option, but have been around over the last decade. Whereas Graphene Coatings are the latest technology to hit the car care industry by storm, boasting enhanced durability and chemical resistance over its counterpart, ceramic coatings. Both are still excellent options and one may suit ones budget more than the other, but if you are adamant on only having the best, then you cannot go past the Graphene Coating.
