McNett Seam Grip urethane repair adhesive permanently seals seams and leaks, repairs tears, and patches holes on tents, packs, sleeping pads and rain wear. Long considered the industry standard, Seam Grip was awarded the prestigious Editors' Choice Gold Award from Backpacker Magazine in 2002. Use Seam Grip to repair surfaces or seal seams of natural and synthetic fabrics, waterproof laminates, leather and vinyl. Seam Grip may be used to repair all types of waders and footwear, neoprene, PVC, rubber, and more. Concentrated and waterproof, Seam Grip offers excellent adhesion, long lasting flexibility, superior traction and abrasion resistance, with minimal shrinkage. When cured (dry) Seam Grip is a very thin, clear, elastic urethane rubber.
Great product. This site was the best price I found. I used it to repair and strengthen some repairs and holes I had on my ILBE pack.
Product is a little too thick. You might consider some thinner if you want a perfect application. Great customer service.
