Not necessarily, you just want to clarify what you are actually getting. Your not getting a full paint correction, which you may or may not want, if the dealer touched the paint, your probably going to need a correction. In many transactions the dealers have tried to run it through the detail shop, and I tell them if they do that I am going to send them a bill for the full correction as those shops fuck paint up. Also never let them sell you the dealer applied ceramic coating, they've done that to me and want to upcharge it. They know they can't remove it, so they take it off the bill.
