Polymarine Sealflex Sealant for Inflatables, 500ml

Polymarine Sealflex Sealant for Inflatables can be used to seal porosity and minor leaks in Hypalon and PVC inflatables. The flexible, water-based acrylic latex sealant is introduced to the inflatable via the valve, where it adheres and cures upon inflation and tumbling to form a waterproof membrane.

500ml is enough for an 8-9ft inflatable.
