What is the main challenge associated with sectioning parts at factory joints?

The main challenge associated with sectioning parts at factory joints is that it limits access to the entire component. When repairs are made at these specific joints, it prevents full visibility and reach to other interconnected areas of the vehicle. This can complicate the repair process, as technicians may not be able to properly assess or address any related issues throughout the assembly, potentially leading to incomplete repairs or missed damage.

In contrast, while creating stronger structural bonds can be important during repairs, it is not the primary challenge of sectioning parts at factory joints. A clean cut is necessary for effective repairs and achieving optimal fit, but this serves more as a procedural consideration rather than a challenge linked specifically to the factory joint's location. Improving corrosion resistance is a consideration during the repair process, but it does not directly relate to the challenges inherent in accessing components through factory joints.
