I think your dealer would be the last people you would want to do the install. Think about what it cost to have service work done at your dealer. There are lots of sign shops out there that are doing it, just find a good one. If you had your dealer do it they would go to a sign shop to have the wrap printed (mark-up) or your dealer would sub contract and charge a mark-up for just making a phone call.
Wraps are images that are printed on vinyl, on large printers. The vinyl is layed over your clean mounting surface, backing material removed, squeegied to remove air bubbles. and then trimmed. If you see a NASCAR race, all of the cars have this vinyl wrap done, a lot cheaper than paint. A lot of younger people are having their street cars done to just change the color or add graphis. When you go to sell the car, just grab a corner and pull, you will be back to your factory paint. No damage done
Do a Google search for your area to see who and how it is done.
