Have a look at some detailing forums, Obsessed Garage, and YouTube videos. Keep in mind, there are lots of "Pro coatings" that only authorized installers can sell/apply that are often tougher and more tedious to apply but are superior in protection and aesthetics.

If I were to go with one consumer coating right now, it would probably be Gtechniq Crystal Serum + EXO with Beadmaker every few washes. Seems to be a well proven setup, I trust Matt @ Obsessed Garage. Gyeon is also top of my list.

This is the set-up I've had on my last 3 ZL1's (Gtechniq) They now have an "Ultra" line as well. It's been a great product. I suspect having a quality installer is half of the battle.
