During the long journey from the factory to the dealership, your car is exposed to a variety of environmental contaminants. It travels on open carriers, trains, or even ships, which exposes the paintwork to industrial fallout, rail dust, and tar. These contaminants bond to the paint and can cause long-term damage if not properly removed. In adition, while a dealership will typically "prep" the car before you take delivery, this process is often rushed and performed by valeters who lack the training and tools of a professional detailer. Their quick wash methods often use dirty towels and brushes, which inflict swirl marks and micro-scratches on your vehicle's paint.
