Premium Seam Sealer from Iosso adds an invisible waterproof barrier with no residue. Use it on stitched areas for natural, synthetic and blended fabrics—without altering the fabric’s color or feel. With the correct seam construction, it’s also effective on vinyl-coated and vinyl laminate materials on boats. The revised formula includes a UV inhibitor to protect thread from extreme 24/7 exposure, and it doesn’t contain silicone or PFAS.
