What are the differences between a wax and a ceramic coating?

The main difference is that Wax Guard is a wax-based paint seal. A wax based seal is never permanent and will eventually disappear. A coating will stay on the car forever unless it is polished off. A coating does fade just like wax. But a coating can be boosted and quickly restored to how it was before. A coating also gives a much deeper shine in the paint and gives a much smoother and more water resistant result.
