USC® 58320 Fiberglass Resin Gel is a one-quart, purple liquid resin formulated for fiberglass lay-up, repair, and bonding applications in automotive bodywork. It provides a high-strength matrix when combined with compatible hardeners.
The gel offers a VOC content of 297 g/L and adheres to a wide range of substrates including ABS, bare metal, fiberglass, plastic, polyester, primer, steel, and wood. Its low flash point of 93.9 °F (34.4 °C) supports rapid cure under standard shop conditions, delivering consistent coverage for structural repairs.
Use requires appropriate personal protective equipment: eye protection, chemical-resistant gloves, protective clothing, and a respirator in well-ventilated areas. Follow the "Warning" signal word guidelines and handle with care to avoid exposure to acute toxicity, aspiration hazards, and skin corrosion risks.
