3M 05877 Reinforced Filler is a high-strength, milled-fiberglass paste designed for structural repairs and fill applications in automotive body work. Delivered in a 276 mL cartridge, it provides consistent flow and easy dispensing for large dents, panel gaps, and reinforcement of weakened substrates.
Key technical attributes include a rapid work time of 3-4 minutes at an application temperature of ≥60°F (15°C) and a shelf life of 12 months when stored unopened. The filler adheres to a wide range of substrates-including aluminum, steel, galvanized metal, fiberglass, FRP, polyester, SMC, wood, concrete, e-coat, and most plastics-making it suitable for mixed-material repairs. Its reinforced formulation delivers high tensile strength and excellent sandability after cure.
Safe handling requires eye protection, chemical-resistant gloves, protective clothing, and a respirator in well-ventilated areas. The product has an 89 °F flash point (closed cup) and is classified for acute toxicity, aspiration hazard, carcinogenicity, flammability, organ toxicity, oxidizer, reproductive, respiratory, skin corrosion, and eye damage.
