What does it mean to repaint one panel?

[OJake]

One panel does not refer to the front, rear, left, or right side as a whole, but rather to a section. If the damage is on the same component, it counts as one panel. For example, on the left side of the car body, if the paint damage is on one door, the entire door will be repainted. If the damage spans two doors, both entire doors will need to be repainted, and there should be no visible repainting seams at the joint between the two panels. Methods for removing black spots on white cars are as follows: Tar: If the black spots are tar attached to the car paint, they can be cleaned using a tar remover. Remember to wear gloves when using a tar remover. Bird droppings and other impurities: If you frequently park under trees, your car will inevitably be exposed to bird droppings or tree sap. If the black spots are caused by substances like bird droppings, they can be soaked with car wash soap or glass cleaner and easily removed once softened. Iron particles: If the black spots on the white car paint are densely packed iron particles, the above cleaning agents will not work. Instead, only specialized clay bars or detailing cloths can be used to slowly polish and remove them after washing the car body.
