Many products exist
Here're the best I know of:
Cancoat
Gyeon One
Carpro lite
Wolfgang SCS
And I believe other brands like Mckee's 37, meguairs, adam's have their own as well.

The main thing for you is to make sure the surface is very clean before application. Whether you polish or not (you should, at least lightly), you'll want to clay bar and then panel wipe before ceramic application.

The good news is that it's never been easier to DIY a coating. They're so much more forgiving and easy to use. Don't forget quality towels - that means 70/30 fiber split. Go for at least 300 weight.

They way you worded your OP, it souds like you're incredulous that there could exist products that last 12m+ well, there certainly are. In fact, most coatings will do 24 months up to 60. Gyeon Pure and Mohs are my favorites.
