First off ask the dealer not to prep the car. Most dealerships will install swirls in the paint for you.
Check to see if the car needs clayed. On a clean surface place your fingers in a plastic sandwich bag, then rub on the paint. If its smooth no clay is required, if you can feel bumps then you should clay.
From the zaino line, I would order the triplets kit which comes with ZAIO, Clear seal and Z8. A $10 savings when you order the kit. I would also add Z5pro and the car wash.
ZAIO
Z5pro- 1 coat
