I would agree with everyone and avoid the dealer. Buy a nice sealant such as Chemical Guys Jet seal or Griot's Paint Sealant and that will basically the same stuff the dealer will apply to your car. To make the paint shine even more apply a good carnuba wax on top of the sealant and you will have a beautiful paint job with minimal effort and save the $699.00, plus you know the quality of the job since you did it yourself.
This is what I have and it has given me excellent results,
