What common issue can arise from poor masking techniques?

The correct choice highlights a fundamental problem associated with poor masking techniques: overspray on unintended areas. When masking is not done properly, whether due to inadequate coverage or improper application of masking tape and paper, paint can easily splatter or drift onto surfaces that are meant to remain unpainted. This not only leads to aesthetic issues but may also require additional cleanup or repainting of unaffected areas, thus increasing labor and material costs.

Overspray can damage surrounding components, create an uneven finish, and undermine the quality of the overall paint job. Proper masking is critical in ensuring clean lines and protecting areas that should remain free of paint, thus ensuring a professional and visually appealing outcome. Effective masking techniques minimize the chances of overspray, leading to a more efficient and high-quality repair or painting process.
