Teroson UP 620 Gelcoat Filler, White, 241g

The Teroson UP 620 Gelcoat Filler is a specialised unsaturated polyester body filler designed for the professional restoration of gelcoat surfaces on boats and glass fibre panels. Its primary function is to repair osmosis blisters and minor surface damage, effectively restoring the original, seamless finish. Once cured, the filler is fully waterproof, making it suitable for applications both above and below the water line, ensuring durable and long-lasting repairs.

This high-quality filler can be applied directly to glass fibre and existing gelcoat. After setting, it offers excellent sandability, allowing for a perfectly smooth surface that can be polished to a high-gloss, factory-like finish. If a colour change is desired, the cured filler can also be overpainted, providing complete flexibility for your restoration project.
