Inland Marine Inflatable Boat Sealant is specially formulated for use with inflatable boats, rafts, kayaks, stand up paddle boards, tow toys and more. This sealant forms a bond with the interior fabric of the inflatable, stopping or "sealing" slow leaks and preventing future leaks from developing. In one easy step, leaks that are virtually impossible to find from the outside are sealed from the inside. Inland Marine Sealant is the only product of its kind which allows for future deflation of your inflatable without the sealant sticking to itself and making re-inflation virtually impossible. Inland Marine Sealant provides a strong bond that seals the leak(s) and keep your inflatable firm for years to come. 1 quart.
