Does repainting car doors affect the vehicle?

Repainting car doors does affect the vehicle. The side effects of repainting car doors include: Damage and deformation of the vehicle's exterior; The quality of the repair cannot be judged solely by visually inspecting the vehicle's appearance and gaps; After a car scrape, the paint film on the metal surface is damaged, exposing the metal layer, which is prone to rust when exposed to rain. The difference between original car paint and repaint: Both original car paint and repaint can meet the decorative and anti-corrosion requirements of the vehicle's surface paint. The original factory paint is applied using robotic arms with fixed viscosity indicators, resulting in high-quality paint surfaces. Repaint, on the other hand, is manually applied in poor construction environments. The main difference is that repaint lacks the electrophoretic layer, only having the color touch-up layer and clear coat layer, which can lead to color discrepancies and severe paint aging over time.
As a long-time car enthusiast, I always believe that door repainting requires caution. After my old Jeep's door got scratched and was repainted once, the color mismatch was glaring – noticeably brighter, like a new hood on an old door. If the paint job isn't done properly, the paint tends to bubble and peel, especially in rainy regions where water seeping into gaps can corrode the inner door panel. Without proper sanding or rustproofing before painting, the new paint won't adhere well, cracking within six months and causing squeaky door closures that compromise sealing. This also significantly devalues the car in the used market, as buyers can instantly spot non-factory work and haggle harder. Choosing a professional shop is crucial—they understand OEM color matching and booth baking processes, ensuring durable and cost-effective results.
