Fiberglass Supply Depot 904-001 Duratec Clear Hi-Gloss Additive for Gelcoat (Pint)

You'll get a superior finish, add quality and save time and labor with Duratec Polyester Hi-Gloss Additive. Low Porosity---when used for repairs, blending the additive with gelcoat produces a low porosity surface. Reduced orange peel---the low viscosity of the blend results in a smooth finish that is easily sanded. Improved properties---for mold surfaces, the blending of the additive with tooling gelcoat creates a higher heat distortion temperature, improved gloss retention, increased impact resistance and reduced subsurface porosity. Superior finish---when blended one-to-one with gelcoats, the additive creates an air-cure, enamel-like coating. No air-dry additive is required. When used for gelcoat repair, surfaces are restored to like-new condition. Use a Non-Wax Gelcoat with this product. Use 2% Hardener in all Duratec products.

• Enhances Gelcoat Gloss & Flow: Designed to be mixed with gelcoat to dramatically improve surface gloss, leveling, and flow-out for a smooth, professional finish.
• Reduces Porosity & Surface Defects: Helps minimize pinholes, orange peel, and surface porosity, resulting in a denser, more uniform cured surface.
• Improves Spray & Application Performance: Thins and conditions gelcoat for easier spraying and brushing, reducing drag and improving overall workability
• Durable, Sandable Finish: Produces a hard, high-gloss surface that can be sanded, buffed, and polished once cured for showroom-quality results.
• Ideal for Marine & Composite Applications: Commonly used in boat molds, marine repairs, fiberglass parts, tooling, and cosmetic composite finishes
