Is rear quarter panel cutting considered a major accident?

[StCharlotte]

Rear quarter panel cutting is considered a major accident. In rear-end collisions, the rear bumper is the most vulnerable part, followed by the rear quarter panel. When a rear quarter panel undergoes cutting and welding repairs, the welded areas are exposed cast iron without paint protection, making them highly susceptible to rust. Specific reasons: While rear quarter panel cutting doesn't affect vehicle handling performance, the cutting and welding repairs require careful application of sealant to prevent rust at the weld points. Since the welded areas are exposed cast iron without paint protection and prone to rust, this qualifies as a major accident. Treatment methods for rear quarter panel damage: The rear quarter panel (also called rear apron) is the second most vulnerable part in rear-end collisions after the bumper. Replacing a rear quarter panel requires drilling out each weld point individually, so the decision between replacement and repair depends on the actual situation. If the rear quarter panel has minor dents, they can be gradually pulled out using a frame or slide hammer without cutting. However, if the deformation is severe, especially if the frame rail is damaged, then the rear quarter panel must be cut out.
