Congrats on the New ride!
No matter which type of finish protection you decide to use the first time will take a fair amount of time to get the job done correctly. Since surface prep is the key, even on a new car, take the time to thouroughly Dawn wash, clay and then protect.
On my last new car I went with Zaino right away and have not regretted it for a minute. The shine is great, durable, cleans up in a snap with Z7 wash and Z6 QD. Initial application takes some time but after that its a breeze to layer on more Z to enhance the look and protection.
The polish/wax route is equally satisfying, but if time is a consideration with regards to maintaining the finish (wax will need reapplication a bit more frequently than a polymer) I give the nod to Zaino :xyxthumbs
