Short Strand Reinforced Filler - 3.78L | BON01160

3M™ Short Strand Reinforced Filler is reinforced with short strand fiberglass to create water resistant repairs that are twice the strength of ordinary body fillers. It is a great solution for repairing holes and rust on metal and fiberglass.

3M™ Short Strand Reinforced Filler is thicker than regular filler, so it requires a bit more effort to mix. Compared to long strand fiberglass filler, short strand filler is also a bit more malleable and softer. Fiberglass filler is great for applying over welded areas and can be used as a build layer where thicker applications of body filler are needed.

• Reinforced with short-strand fiberglass for strong repairs
• Repairs rust-outs and shattered fiberglass
• Use as a foundation under regular body fillers for strength
• Can be used with Bondo® Fiberglass Mat and Cloth
