Review: Stick this where the sun don't shine! (i.e. wet leaky seams) - excellent product. - Excellent product for seam sealing and patching. I primarily bought this to apply a patch to a significant patch for my nylon tent and after 24 hours it made a good solid bond which dried perfectly clear whle remaining flexible. I had some stitching to support the tear and used this to seal the stitching afterwards. I personally tried thinning it with white spirit to pentrate the stitching better but still found it very thick though it worked well. I found it a bit sticky for seam sealing though it was very effective. Bonding and grip was excellent. Tubes just a bit small for a major repair (hopefully a rare event for any camper) and quite expensive - I would have liked to be able to but a larger tube size despite cost. Primary lesson is not to rip my tent so badly next time! Excellent for restoring the seams in a worn out old tent. Review: Works - Worked great for sealing the seams on my motorcycle trousers. Its like a gel and just spread it on with the supplied brush. Cheers ## Features - Causes serious eye irritation. - Causes skin irritation. - Contains isocyanates.

Its like a gel and just spread it on with the supplied brush. Cheers ### ⭐⭐⭐⭐ Good for leaky seams... *by N***L on 1 May 2025* I bought 2 tubes to reseal and MSR Elixir 3, which had deteriorated flaking seam tape. I applied (purposely) to the outside of the tent, which may not be as aesthetically pleasing but beats spending hours trying to remove all the old seam tape. Annoyingly one tube was about a third cured before even breaking the seal, so only had about 2/3 usable sealant. I applied with a small syringe and a brush rather than the enclosed brush/ cap thingy, as from previous experience they make too much of a mess. The glue seemed thicker than when I have used it before and became quite tacky quickly on a 25c day making it a little difficult to get on. Second tube was better but still a little thick in consistancy. Apparently you can thin this a bit with acetone, but I didn't bother. Check out Dose Of Dirt on YouTube for Your Tent Is Not Waterproof and TheOutdoorGearReview for his seam sealing tips. And as per GearAids advice allow to dry fully then coat in talc to stop it sticking to itself when packed away. Oh and you're supposed to apply to the inside of the tent ## Frequently Bought Together - GEAR AID Seam Grip WP Waterproof Sealant and Adhesive for Jackets, Tents, Sleeping Pads and Outdoor Fabric | Repairs Rips, Seals Seams on Nylon, Canvas and Vinyl - GEAR AID Tenacious Tape 3”x20” Fabric and Vinyl Gear Repair Tape, Quickly Fix Holes and Rips in Puffy Jackets, Rain and Snow Gear, Tents, Sleeping Bag and More, Clear, 1 Pack - GEAR AID Tenacious Tape Repair Patches for Jackets, Tents, Outdoor Gear and Technical Fabrics, 3” Rounds, 2.5” and 1.5” Hex Shapes, Color and Size Options, Black --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/49609937-mcnett-seamgrip-seam-sealant](https://www.desertcart.co.uk/products/49609937-mcnett-seamgrip-seam-sealant) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-08*
