Works well. I did not have issues with seams, but wanted to prevent that. Easy to apply when tent is upright. Very water resistant. Looks fine. I wash my tents in my washer and the seams have no problem. I aired out the tent after application.

Brilliant ! My gazebo leaked between the seams over our furniture. This has worked a treat. It appears to be holding up at the moment. Only time will tell how long it lasts for.

I recently used this sealant on a tent with some pretty bad seams, and it worked wonders. Applying it was a breeze. It went on smoothly and dried quickly, which was a relief since I was on a tight schedule. What impressed me the most was how well it sealed the seams. They feel sturdier now, and I’m confident this sealant will outlast the tent itself.However, there are a couple of things to note. While the application was straightforward, the 2 oz size might not be enough if you have a larger tent or multiple items to repair. I only had a few and I used quite a bit. I may have not required that much, but I wanted to be sure. Also, it’s important to apply it carefully to avoid any mess since it’s quite sticky.Lastly, I’m really pleased with how effectively and quickly this fixed the seams on my Montana tent. It’s a handy product to have for any camping enthusiast dealing with seam issues.

Easy to use and while I have not had the tent out in the rain yet, think it should perform as advertised. My only complaint is that you have to use it all at once because once the liquid dries on the applicator the lid is clogged and the rest of the liquid will not flow. I ended up using a piece of paper towel to finish the job an hour or so later but it was very messy and I had the liquid all over.

The product is very runny. At first I tried applying it with the tent set up and the fly inside out. It worked ok, but it was very messy as this comes out watery and will drip/run easily. The second time I tried applying it, I set the fly on a table so it would be more flat. It worked better, but I wish this product were easier to apply.

Used on an older Easy-Up Canopy then the original seam seal tape was giving up the ghost.I removed the cover from the frame and flattened it out on the lawn. Pulled off the remaining loose tape and applied the sealer solution.It does go on thin but simply coated the seams and let in dry. In direct sunlight on a nice day it took around 4 hours to dry.Tested with a hose directly on the seams and had zero leakage.Happy with the results.

I got caught in a torrential downpour in Hawaii, and my 20 year old Sierra Designs tent that had never leaked let a puddle accumulate. I used this on the fly and the base of the tent, and it stayed dry with a solid hose test and in a fairly strong (but brief) rain last weekend camping. In all fairness, I also re-coated the fabric, so I'm not sure which had the leak to begin with.The other reviews really trashed the applicator, so I wanted to say my piece on that. I felt like it worked ok. Not great, but ok. If you want your seams to look perfect, maybe use a small sponge applicator (maybe from the paint section at your hardware store or something from an art store). For a garment, this may be too messy. For a tent, it was fine. I just used a moist rag to clean up a few drips and runs. It wasn't factory-perfect, but it was good enough for a tent.Instead of ripping off the seal on the bottle, try puncturing it finely. I ripped it off and felt like the applicator tip was fine, but the flow of liquid was too fast, leading to drips. If I could have slowed it down, it would have been much better.Also, use a strong headlamp. The more light you have, the easier it will be to see what you're doing. I did this in a carport on a fairly dark day. I was ok doing the rain fly, but when I went inside the tent, it was too dark. When I added more light, I found it was a lot easier to get the right amount of liquid on. In the dark, I was over-applying, and it was messier.Note that the bottle has some scary health messages about this, so use caution. I put on safety glasses and rubber gloves to apply.

Vor kurzem habe ich "Tenacious Tape" bestellt. Bekommen habe ich "Seam Sure", ein anderes Produkt von Gear Aid. Daraufhin habe ich eine Rezension geschrieben die diese unglueckliche Verwechslung wiederspiegelt, Mit anderen Worten, eine "Eins" was auch berechtigt war. Es stellte sich aber heraus, das dass ganze ein Fehler in der Beschreibung durch Amazon war, und nicht des Verkaeufers. Aber einen Tag spaeter rief mich der Verkaeufer ( aus Kalifornien ) an und wollte wissen warum ich unzufrieden mit dem Produkt war. Nach einem laengeren Gespraech wurde uns klar wo der Fehler lag und der Verkaeufer versprach es zu beheben. Und siehe da, heute kam das bestellte "Tenacious Tape" mit der Post. Das nennt sich "Exemplarische Customer Service".Man traeumt von solchen Firmen die das Belangen des Kunden so in den Vordergrund stellen. Nach dieser Erfahrung wuerde ich sofort wieder von Dolphin Scuba Center in Sacramento bestellen. Eine 5 als Bewertung reicht nicht aus um meine Zufriedenheit auszudruecken.

Applied this sealant to my Wilderness Logics Tadpole Tarp this evening, I had researched the sealants and am glad I did.Look up your material and get the right stuff. If you have a Polyester/Nylon based tarp, this is the stuff for you.If you have a Silicone/Nylon (Silnylon) Tarp, it is not. Look for a silicone based sealant.I'll take it out this weekend (with the expectation of rain) and give it a test run.It applied easily enough, make sure the tarp is tight as you apply it, as it needs to fill in the sewing holes in the flat-felled ridge seams. I added a second coat approx 30 min. after the first, it didn't peel up the first coat at all. If you have tie-outs on your tarp, I'd coat both sides, as these can have bigger holes than a normal center ridge seam.The only complaint I had was the brush itself, to me it seemed a little coarse, but at a 1/2", it worked well at spreading the product on the seam. My preference would have been a finer, less stiff bristle set, but not a big deal. Taking care not to apply too much is the key, as it can be difficult to see the sealant coming out of the center hole.When done wash the brush under cold water BEFORE it dries on the bristles. No cleanup info on the packaging. Overall a 5 star product...So far...UPDATE:2 Aug 12Tried the seam sealer and let it dry per manufacturers directions. Stored tarp for about 2 weeks before I got a chance to use it.When I unfolded the tarp, the glued seam stuck to itself a little and peeled a small amount where it was painted on. This didn't ruin the tarp or the applied product, just thought it was noteworthy. I coated both sides of the tarp where it had tie-outs. I asked for the maker to provide them on both sides.While it did rain heavily for approx 30 minutes, the tie-out fabric was still a litle damp, but sealing the tieouts decreased the amount of water considerably.Tie-out tabs were damp, but not dripping as they were prior to sealing.Product does the job well, as long as the end user applies it to a clean surface and takes care to do the job carefully.Still a five star product in my book!
