Love the ceramic spray coating from turtlewax hybrid solutions. Been using it since my previous car and since day 1 on my sonata. It leaves a nice shine/slick feel, makes cleaning a whole lot easier, and is extremely easy to apply. They last through washes as well. I've tried a lot of spray coatings and I'm always back to using these.
I do eventually want to try these though, but hard to justify the cost: Graphene Ceramic Spray Coating™ Advanced
