It's a multipurpose, non-sag 1-component polyurethane sealant and adhesive ideal for interior marine repair work. The highly elastic formula works well in areas of high vibration to flex with the movement and maintain a strong bond. It's solvent-free and low-odour for more comfortable use inside the craft and can be overpainted once dry for a professional look. Apply using a hand or mechanical sealant gun and tool within the 60-minute skin time. It will be fully cured to a fresh and seawater-resistant finish in 24-48 hours. Also available in White and Grey.
