Are graphene coatings better than ceramic coatings?
In theory, they are stronger and should last longer. The science on coatings hasn't been wrong so far, but only time can tell, and graphene coatings haven't been on the market long enough for anyone to compare in a real-world test on durability.
There are however differences between graphene and ceramic coatings. Our graphene coating appears thick compared to ceramic, and in the bottle it has a smokey tint, which on the car does appear to deepen some colours. Water seems to bead up differently with graphene... at least with our graphene, which fits with the promise that it's more hydrophobic. It's claimed that it's high conductivity means it's anti-static. Are any of these properties better? They certainly aren't worse.
