The body shop wants to give you extra clear coats, right? The real reason
is: they want to blend the new paint with the old by spraying and
feathering the base coat half way into the front door. Your eye never
looks for slight color variations in the middle of a door versus the line
between the fender and the door. If it was my car, I would say no and
make the body shop match the paint perfectly as possible. Seven year old
faded paint can be a bear to match, depending on the color. Good luck.
