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.

The container appeared to have been opened prior to shipping. And leaked in the wrapping and box.
