The Ceramic + Wax sprays last 6 to maybe 12 months if you're lucky. I use Adams Graphene, which lasts up to 24 months (Advanced Spray), and clean or detail with CS3, unless really dirty, then wash. With the draught here on the east coast, we're not supposed to wash the car, and CS3 works as a waterless car-wash, and boosts the Graphene/Ceramic coating. - Leaves a nice shiny mirror like shine, when you prep the surface prior to the initial coating.
