Size:16 oz. Dura Seal - Permanent, Rapid Curing Instant Leak Sealer. 3X:Chemistry Dura Seal is an instant leak sealer and coating that adheres to most substrates. Dura Seal features a superior, fast setting, rapid curing spray on elastomer with UV resistance that provides a flexible - no crack, no peel - coating that is paintable and long-lasting. Once cured, it will help prevent rust and corrosion and its anti-fungal formula stops mold and mildew growth.

Dura Seal provides up to 5 years of protection and withstands extreme temperatures of -30 degrees Farenheit to 200 degress Farenheit without cracking and pealing. The elastomer coating remains flexible after drying with elongation up to 500%. Allowing it to accommodate substrate movement, including shifting, expansion and contraction.
