A quality ceramic or graphene coating lasts years, not months — but the real number depends on the product, how it was applied and how the car is washed afterwards.
Cheap 'ceramic' spray sealants might last a few months. A properly applied graphene coating like the Onyx system we use is a different category — it's rated for years of protection when it's cured correctly and maintained sensibly.
The biggest factor after application is how you wash the car. Two-bucket hand washing keeps a coating slick for its full life; automatic brush washes and dirty mitts drag it down early. We'll show you exactly how to look after it, and offer a maintenance check to keep it topped up.
