Two-Component White Gelcoat 4-in-1 (Osculati) – Filler and Finish for Surface Repairs

This two-component 4-in-1 gelcoat by Osculati is an innovative solution for quick and high-quality gelcoat repairs. Its formula combines the properties of a filler and a finishing gelcoat, meaning you can use it directly to fill damage and achieve a smooth, glossy finish without needing a separate topcoat. After mixing the base with the hardener, the product applies easily with a spreader like a standard putty.

The end result is a hard, bright white coating that restores the original look of scratched, chipped, or worn areas. "4-in-1" signifies that this product delivers four effects in one: it fills, levels, provides a glossy finish, and protects the repaired spot. The cured layer is highly durable and long-lasting, comparable to the factory gelcoat.

• Easy repairs: Ideal for fixing small defects on hulls and decks – docking scratches, minor impacts, gelcoat cracks. Simply clean and dry the damaged spot, mix the components, and apply with a spatula.
• Fast curing: Dries in about 1 hour at ~25°C, allowing quick turnaround and minimal haul-out time. After full cure (a few hours), the surface can be lightly sanded to fine-tune the level if necessary.
• Waxed finish: The formula includes wax (paraffin) to ensure a thorough cure with a gloss finish. No additional topcoat is needed unless you choose to paint over it for color match or extra UV protection.
• Versatile use: Can be used on all fiberglass (polyester) surfaces – boat hulls, jet-skis, RV and camper panels, etc. It tackles stubborn blemishes and wear, restoring both functionality and appearance.
• Tips: Do not use on clear glass or natural leather materials. For best results, work in moderate temperatures and follow the package mixing instructions (the entire ~200 g kit is portioned for a typical small repair job).
