The car door has a minor scratch, should it be partially or entirely repainted?

The car door has a minor scratch and needs to be entirely repainted; otherwise, there will be color differences. On the same object and plane, even a slight color variation can be very noticeable. Once color differences occur, the paint surface will look like a patch, appearing very unattractive. Therefore, except for the front and rear bumpers, which can be partially repainted, the rest must be repainted as a whole surface. Relevant details are as follows: Standard automotive paint process: The standard automotive paint process includes inspecting the lines, flat (arc) surfaces, gaps of the repaired sheet metal parts, sanding and finishing beveled edges, dust removal, cleaning, masking, applying primer, filling with putty, sanding putty, applying masking paper, spraying intermediate paint, sanding intermediate paint, removing fine dust from the car body, spraying solid color topcoat, spraying base color paint, clear coat spraying, baking, waxing, and polishing. Process requirements: Most automotive repair units in China perform body surface paint repairs using manual single-vehicle operations. To ensure the quality of the body surface paint, automotive spray painting equipment is generally required. Spray painting and baking booths are produced by several manufacturers and come in large, medium, and small sizes. Large ones are suitable for group buses, medium for minibuses and travel vans, and small for cars. When small equipment is unavailable, medium or large ones can be used as substitutes.
