Can Sheet Metal Repair Achieve the Original Factory Effect?
1 Answers
Sheet metal repair cannot achieve the original factory effect. The quality of a car's paint surface is not only determined by the paint itself but also by the spraying process and the limitations of spraying conditions. Most painted car exteriors have deformations and generally require sheet metal correction, which can compromise the performance of the metal substrate. Modern cars mostly use steel plates with a double-sided galvanizing process, followed by surface heat treatment to enhance the metal's strength and hardness. However, after sheet metal repair, the galvanized layer on the surface is damaged. If heating is used during the sheet metal process, the metal material may undergo annealing, significantly reducing its strength and hardness.
