What is a characteristic of lightweight fillers?

Lightweight fillers are designed to offer improved handling characteristics compared to traditional fillers. This means they are easier to mix, apply, and sand, which enhances the overall efficiency of the repair process. Their lightweight nature allows for better control during application, reducing the risk of sagging or running, and making them more user-friendly for technicians. This characteristic is particularly valuable in auto body repair, where the quality of finish and ease of application can significantly affect the outcome of the restoration process.

The other options do not accurately describe lightweight fillers. For instance, they are typically lighter than traditional fillers, not heavier. Additionally, lightweight fillers often require less curing time compared to conventional fillers, allowing for quicker turnaround on repairs. Finally, while some fillers may be specialized for certain conditions, lightweight fillers are generally versatile and can be used in a variety of applications without being restricted to specific conditions.
