When I got my wife a Pilot last year they said they put on paint protection, leather protection, undercoat, nitrogen in the tires and tinted the windows for like $1100. I said im not buying anything I can't see, they took off everything but the tint. I told them to deflate the nitrogen and refill with shop air if need be (they wanted $100 for nitrogen!) I use to work on airplanes, they only need for nitrogen is if you are going from -60 to 100 degrees in minutes.
Anyway find a reputable detailer and get paint coatings if you want.
