U-POL UP0745 Flyweight Gold is a premium lightweight polyester body filler designed for smooth spreading, fast curing, and long-term stability. Its smooth as butter consistency allows easy application without dragging or pinholes, while the Bi-Cure adhesion system enables direct-to-metal bonding on steel, galvanized steel, aluminum, OEM paint, fiberglass, and most plastics. Flyweight Gold cures quickly, becoming solvent-impervious and ready to sand, prime, or paint in 15 to 20 minutes. The non-porous formula is engineered to be shrink-proof and pinhole-resistant, ensuring a stable repair surface that remains easy to sand even after extended curing. The product comes in a 3-liter container, includes cream hardener, and has a VOC content of 30 g/L.
