In collision repair, what does "paint blending" refer to?

Paint blending refers to the technique of seamlessly integrating new paint with existing paint to create a uniform finish. This process is crucial in collision repair, especially when a vehicle's panel needs repair or refinishing due to damage. The goal is to ensure that the transition between the newly painted area and the original paint is as smooth and invisible as possible. This often involves matching the color, gloss level, and texture of the original paint, allowing for a harmonious appearance that can withstand the scrutiny of potential observers.

The other options, while related to various aspects of the painting process, do not accurately capture the essence of paint blending. Applying primer is an essential step in preparing a surface for painting but does not involve the integration of colors. Mixing different types of paint for custom colors plays a part in achieving specific shades but is not focused on achieving a uniform finish with existing surfaces. Lastly, using multiple paint guns for different textures may refer to a technique in applying paint but does not specifically address the integration of new and old paint that paint blending entails.
