What could explain the thicker paint?
A door may have been repainted because of a scratch or following damage that first required repair. Paint thickness alone does not distinguish between these causes. Further measurements on the panel and surrounding areas, together with the vehicle’s condition, help put the finding into context.
The vehicle, paint system and panel all affect thickness. 120 µm is not a universal target, and 280 µm is not a fixed threshold for accident damage. What matters is how the readings compare across that particular vehicle.
