What is a common name for exterior moldings?

The term "reveal molding" is commonly used to describe exterior moldings on vehicles. This name refers specifically to the design and function of the moldings, which are typically installed around the edges of windows, doors, or other exterior surfaces to enhance the vehicle's aesthetics and provide a finished look. Reveal moldings help to define the outlines of various components on the vehicle's exterior, contributing to its overall visual appeal and providing protection against elements.

While the other terms—trim molding, seal molding, and edge molding—can refer to different types of moldings used in automotive design, "reveal molding" is the specific term that is widely recognized for exterior applications, thus making it the most accurate answer in this context.
