Gear Aid Seam Grip Sealer is a urethane repair adhesive that works on all types of fabrics and surfaces, including neoprene, PVC, rubber, leather, vinyl, polyurethane and other synthetics. This versatile adhesive is washable, flexible, dries clear, and is unaffected by heat and cold. You can use it to repair leaky waders and footwear, rainwear, and tents. Gear Aid Seam Grip Sealer is perfect for sealing seams, repairing tears, and patching up holes, but really it's so much more: it waterproofs tents, improves traction, and even offers abrasion resistance. It really is a gear repair kit in a bag! One tube can seal all the seams on an average 2-person tent.
