What is the major risk of neglecting chemical incompatibility when repairing?

Neglecting chemical incompatibility during repairs can indeed lead to material breakdown and poor outcomes. When different chemicals or materials are used that are not compatible, several issues can arise. These may include weakening of the bond between components, leading to structural failure or degradation of the materials involved. For instance, if a repair adhesive is not compatible with the substrate or the coating being applied, it may not adhere effectively, resulting in peeling, cracking, or delamination.

Furthermore, chemical reactions between incompatible materials can generate heat or cause expansion, impacting the integrity of the repair. The ultimate result is often a repair that does not perform as intended, resulting in increased labor and material costs to rectify the situation, along with potential safety hazards if the repair fails in a critical area of the vehicle. Hence, it is crucial to ensure compatibility among all materials used in repair processes to achieve durable and effective results.
