Flexible. Will touch it up before next season.

I know most newer tents are much better at staying waterproof than older versions, but unless they have sealed seams, they're eventually going to leak. It's well worth the effort to seal the seams when you have the tent setup.I last sealed the seams several years ago, and they held up very well with using the tent a few times a year. Since I needed to set it up to air it out after a particularly rainy trip, I ordered more sealer and did them again. I saw no leaks or issues, but it was worth the cost for another few years of waterproofing.

To start, this product definitely works and prevented any leaking during my camping trip…but I have never seen a more terrible product design in a while. To get the product out, you have to turn it upside down and squeeze it out, but then have to put it right side up to brush it on so it all just drips onto your hands and everywhere within a 5 mile radius. Once it dries, you then turn into a bearded dragon during its shed cycle and you have to peel off what looks like an outer layer of skin. While camping, we experienced a slight drizzle, with no leaking (I know it isn’t saying much, but still…no leaks!) overall I think this product definitely accomplishes its purpose, but make sure you have towels down if the tent is up, and make sure to have a paper plate to dab the excess off.

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.

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.

Sealant appears to be of a fair quality. The applicator is horrible. There is a lingering after product use Smell that seems to linger for a very long time after application to my tents which is very anoying, even after ample ventilation post application. Because of the smell, I'd look for another product.
