Why don't people opt for partial paint touch-ups?

Partial paint touch-ups may result in color discrepancies. Partial touch-ups: There are generally two methods for repairing vehicle paintwork: one is touch-up painting, and the other is full panel respray. For minor scratches, most repair shops will only fix the damaged area and its surroundings, known as touch-up painting. The advantages of this method are obvious—it's quick, simple, and material-saving. However, the drawbacks are equally apparent: it may affect aesthetics, show color differences under sunlight, and potentially leave uneven paint surfaces after repair. Full panel respray: Except for the front and rear bumpers which can be painted halfway, all other panels require full respray. If the scratch isn't severe, polishing and waxing may suffice. However, if the primer is exposed or the damage is deep, the entire door panel needs respraying. Partial resprays often show severe color mismatches—sometimes it's better not to paint at all.
