You would be surprised how much prep work is required even on a brand new car. These cars sit at the dock, on the boat, and at the VPC centers non covered and filthy for months with all kinds of debris coming in contact with the paint.

Any professional who is worth anything will do a full paint correction before applying coating. You see quotes all over the place because like anything it depends on the quality of work done, and also every vehicle is different depending on the condition of the paint.
