No an expert but I can’t see why it needs to be that massive of a fix, painting the whole side? that area seems shaded by the door slot contour so maybe try a smaller fix and any blend mismatch will be hidden by the contour. I would at least ask if they can protect upper side of that lip where the sun hits and do a really small localized blend, sand smooth and blend clear in just the inside of the notch area.Not necessarily keeping me up at night. Just frustrating too even be their in the first place.. it does show when the door is closed also.
