USC® Long 'N Strong™ Body Filler (1 gal olive-drab) is a high-strength, two-part polyester filler designed for structural repairs and panel reconstruction in collision work. It bonds to a wide range of substrates-including ABS, aluminum, steel, fiberglass, wood, concrete, SMC, plastic, and bare metal-providing a versatile solution for both metal and composite panels.
The formulation delivers low VOC emissions at 275 g/L and offers a flash point of 93.9 °F (34.4 °C), supporting safe handling in typical shop environments. Its broad substrate compatibility reduces prep time, while the olive-drab pigment aids visual blending before sanding. Proper personal protective equipment-eye protection, chemical-resistant gloves, protective clothing, and a respirator-is required, and adequate ventilation should be maintained due to acute toxicity, aspiration hazard, and flammability.
