Which of the following is NOT considered a type of paint failure?

Color damage is not considered a type of paint failure because it refers specifically to a change in the appearance of the paint, such as fading or discoloration, rather than an actual structural or functional defect in the paint film itself. Paint failure typically involves issues that compromise the integrity or protective qualities of the paint, such as peeling, cracking, or blistering, which can often lead to underlying substrate deterioration.

Friction damage and impact damage are more closely associated with mechanical incidents that cause direct harm to the paint layer, leading to failures that require repair. Surface coat generally refers to the protective layer of paint, and while it can show signs of wear or damage, this wear indicates potential failure modes that affect performance. The distinction of paint failure lies in its effect on the paint's ability to protect surfaces, which color damage does not inherently compromise.
