Ceramic wax is not the same thing as a ceramic coating.
Ceramic wax is a wax with some sio2 added. It's not expensive and can be used by anyone that has applied wax or polish before. True ceramic coating is a semi permanent coating/sealant that with the proper maintenance, will last for years. It's not necessarily meant to be applied by a novice as the application can be screwed up pretty easily. It also requires that your paint be as perfect as possible before application. The reason is that it won't cover up swirls and scratches.

The ceramic technology is progressing pretty quickly. sio2 was the go to but now it seems that Graphene is the new hotness. Beware though, a lot of this(including the word ceramic) is just a buzzword that makers use. There are good and bad ceramics out there so do your research if this is something you want to do.
