Flex Paste is a high-quality rubberized paste designed to effectively fill and seal large gaps, cracks, and holes, providing a reliable solution for various repair and sealing needs. Its super thick consistency allows it to cling tightly to surfaces, ensuring maximum adhesion and filling capacity. Once fully dry, Flex Paste transforms into a strong and flexible rubberized coating that creates a durable barrier against air, water, and moisture, safeguarding surfaces and objects from potential damage.
