A coating, sealant or wax only protects your paint as long as you maintain it. Washing safely, topping up in time and decontaminating now and then keep the water-repellent performance up and extend the lifespan considerably.
How often that needs to happen depends on your car. A daily driver parked outside that covers a lot of kilometres catches more dirt, brake dust and UV than a garaged weekend car. That is why this schedule factors in your usage and mileage.
The intervals come from coating and wax manufacturers and experienced detailers, not from guesswork.
