As a car buyer I would love to have had that option. Instead, my dealer talked me in to a product called CilaJet. At the time, I knew nothing about detailing. I joined this forum AFTER I bought my dream car ('13 BMW 650iX) After a few minuted on the forum I realized I had made a $900 mistake. The car was three years old and the paint was in fairly good condition, but far from perfect. The "detailer" clayed the car and applied the coating. After I learned how to look at paint, I discovered the swirls, RIDS and marring that were now happily sealed under this product.
So, I joined Autogeek, purchased a Flex and a variety of products (Megs, Pinnacle, Menz, WGDGPS) and buffed off the coating and improved the paint to about 90%. I would never purchase an option like that again, but if I had a chance to get a new car polished and coated by a true professional detailer, I would jump at the chance.
I learned that this service is really just a profit center for the dealer. Too bad, but at least I learned how to care for my paint. Thanks Autogeeks!
