Comparing FORTIVO's Top Polyurethane Sealants

This category features two standout products tailored for specific repairs, helping you choose based on your needs.

Its paintable, quick-set formula excels at filling gaps and seams, including RV roofs, preventing leaks and corrosion. It includes gloves and a precision tip for clean application, making it ideal for bodywork and underbody sealing.

In contrast, the Polyurethane Windshield Adhesive offers 310ml in black for auto glass repairs.
