Overview
Built for the booth.
USC® Garage multi-purpose filler is a creamy bodied filler with a smooth texture that is easy to spread and sands to a fine featheredge. The tack-free, clog-free, and non-sag formula is perfect for repairing vertical surfaces.
USC® 77701 Multi-Purpose Filler is an 8 oz off-white liquid filler formulated for high-performance repair of a wide range of automotive substrates. It is designed for body shop technicians who need a versatile, sandable filler that bonds to metal, plastic, wood, and composite surfaces.
Key technical features include a VOC content of 215 g/L and an approved application temperature up to 200 °F (average). The formulation adheres to ABS, aluminum, fiberglass, galvanized steel, OEM plastics, polyester, primer, SMC, steel, and wood, providing consistent fill and coverage across diverse repair scenarios. Its low viscosity promotes easy flow into fine cracks while maintaining sufficient body for shaping before sanding.
Safety is critical: the product carries a "Warning" signal word with acute toxicity, aspiration hazard, carcinogenicity, eye damage, flammability, organ toxicity, oxidizer, reproductive and respiratory hazards. Use eye protection, chemical-resistant gloves, protective clothing, and a respirator in a well-ventilated area. Follow standard first-aid procedures for inhalation, skin contact, eye exposure, or ingestion as outlined in the SDS.
