A two-component polyester spray filler (putty) for quick and uniform leveling of large surfaces.

It cures fast (around 3 hours) and sands easily to a smooth surface – the perfect base for primer and paint.

• High build capability – forms a thick layer that hides small defects and waves in the surface
• Fast curing (~3 hours at 20°C) – speeds up the repair process and saves time
• Easy to sand to a fine smoothness – sands uniformly with minimal effort, creating an ideal paint-ready surface
• Available in kits: 1kg (with hardener, for small repairs) and 10kg (for large projects or entire hulls) – choose the size to fit your needs
