What happens when a vehicle has a static charge caused by rubbing with wipers?

When a vehicle acquires a static charge due to friction, such as from wipers rubbing against the surface, it creates an electrostatic effect that can attract small airborne particles, like dust and dirt. This phenomenon occurs because static electricity induces an imbalance in electrical charges, leading to a slight attraction of nearby particles which may settle on the vehicle's surface.

This is particularly relevant in painting and refinishing work, as these attracted particles can become contaminants during the painting process, potentially leading to imperfections in the final finish. It's essential to ensure that surfaces are adequately cleaned and grounded to mitigate this issue before any painting work commences.

While the other options mention effects like improved adhesion, cracking, or painting prevention, they do not accurately relate to the direct consequence of static charge from wipers, focusing instead on separate issues that may arise in the painting process.
