If your car's paint isn't damaged or if you do not have any swirl marks, ceramic coating is way easier than applying a coat of wax.
It is pricy bec most detailers will have to do a full paint corrections before applying ceramic coating.
I did mine in less than 2 hrs but my paint was perfect.
Highly recommended as others stated.
