Advantage: Ceramic coating offers good protection to the car's surface. The nano-coating can protect the car from most scratches, dirt and chemical contaminants. Ceramic coating also doesn't have any side-effects to the original paint. Ceramic coating also lasts longer than regular paint.
Disadvantage: On the very low end as far as professional ceramic prices you can expect to pay at least $500 for just the application. Ceramic coating application takes time. If you plan to do ceramic coating on your car, be ready to leave it at the detailing shop for at least three days. Also, if not done correctly or professionally, ceramic coating might look worse than the original paint finish of your car.
Hope this helps
