How Long Does Ceramic Coating Last?
Updated October 9, 2026 4 min readBy Dominick, owner of Slums Mobile Detailing
Coating lifespans are advertised anywhere from 1 to 10 years. The real number depends on the product, the prep, and how the car is treated afterward.
How long does ceramic coating last?
A professionally applied ceramic coating typically lasts 2 to 7 years. Slums installs a 6-year coating. Real-world life depends on prep quality, how often the car is washed, whether it sees brush car washes, and exposure to winter road salt and sun.
What shortens coating life
- Poor prep — coating over contamination fails early
- Automatic brush washes
- Harsh, high-pH soaps and degreasers
- Leaving salt and bird droppings on for weeks
How to make it last
Wash every 2–3 weeks with a pH-neutral soap, dry with clean microfiber, and remove droppings and sap quickly. That's it.
