Understanding What Bondo Metal Reinforced Filler Is
Bondo Metal Reinforced Filler is a two-part polyester filler designed specifically for repairing metal surfaces. Unlike regular fillers, it includes metal reinforcements that give it superior strength and adhesion. From my experience, it works well on car bodies, metal panels, and even industrial equipment.

My Tips for Using Bondo Metal Reinforced Filler
