Bondo® Short Strand Fiberglass Reinforced Filler SS-PT-ES, 21 oz (595.34 g), 8 per case

Bondo® Short Strand Fiberglass Reinforced Filler makes an excellent foundation for hole, dent and rust-out repairs without the need for backing strips, cloths and resins. It contains short, interlocking fiberglass strands and fibers that make it stronger than regular body filler. It is also slightly thicker and provides a fast drying time, making the filler less messy on vertical surfaces like car doors.
