first things first... clay the car and remove all particles stuck to your car.
second, fix the imperfections in the clear coat (swirls, scratches, etc)
then third, wax or seal it with your perference...

shine comes from clarity of the paint, not the wax (in fact wax doesn't give any shine, even if its zaino)...

my choices in products:
- dawn wash to remove all waxes from the dealer
- claymagic clay bar to remove small particles
- 1z or Menzerna polishes to fix the clear coat using a porter cable with various pads
- klasse all-in-one and sealant
or
- p21s carnuba wax
