Product Description

904-001 Duratec Clear Hi-Gloss Additive for Gelcoat (Quart)

PROFESSIONAL HIGH-GLOSS GELCOAT FINISH – Converts gelcoat to an air-cure formula that dries to a smooth, porcelain-hard, high-gloss surface without requiring wax additives or PVA. Perfect for marine restoration, mold work, and cosmetic gelcoat repairs.
SPRAYS LIKE PAINT FOR EASIER APPLICATION – Reduces gelcoat viscosity for improved atomization and smoother spray patterns. Helps gelcoat flow evenly while minimizing orange peel, craters, and surface imperfections during application.
IMPROVES REPAIR QUALITY & REDUCES POROSITY – Enhances air release and creates a flatter, smoother profile for easier sanding and polishing. Excellent for fiberglass boat repairs, plug manufacturing, tooling gelcoat upgrades, and resurfacing projects.
FAST CURING & EASY TO SAND – Designed for rapid air-cure performance with gel times around 14–18 minutes when catalyzed properly. Creates a hard, sandable finish that polishes to a deep gloss with reduced labor time.
VERSATILE FOR GELCOAT REPAIRS & RESURFACING – Compatible with most gelcoats and can be blended at multiple ratios depending on opacity and finish requirements. Ideal for boat hulls, decks, molds, plugs, marine restoration, and fiberglass fabrication applications.
MULTIPLE BLEND OPTIONS FOR CUSTOM RESULTS – Use a 50/50 mix for standard repairs and resurfacing or a 25/75 blend to maximize gelcoat hide and color opacity. Flexible mixing ratios allow users to fine-tune gloss, coverage, and finish quality based on the application.
DESIGNED FOR EASY CATALYZING & CONSISTENT PERFORMANCE – Mix with full-strength MEKP catalyst at a recommended 2% ratio for reliable curing and predictable spray performance. Formulated to blend smoothly with gelcoat while maintaining excellent flow, adhesion, and sanding characteristics.

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.
