Easy Application, No Leaks
I used this to seal my tent. Worked perfectly but it definitely took a awhile. I think it was worth the savings instead of having the manufacturer seal the tent for me. I also didn't have any issue with the seams sticking to each other once I put the tent back in its stuff sack. No leaks so far after a year of use (4 trips). I would also recommend a few dots of this on the bottom of a sleeping pad to prevent sliding on the tent floor.

Worked well for seam-sealing a one-man nylon tent
Easy to use, applied it to my one-man nylon tent, which has not let any water since the application in three backpacking trips, one which involved some heavy nights of rain in the high mountains. Reasonably priced. Not sure if there would be enough product to do a two-man or larger tent. There was was a little more than I needed for a one-man tent. Recommend.

Worked well on SilNylon tent
I used this to reseal the seams on an older Tarptent Rainbow tent - Note I am referring to the silicone coated nylon model of the tent. This is a great tent that I have used on both the Appalachian trail and the Pacific Crest Trail. I diluted the silicone sealant to a 50/50 mix with mineral spirits before applying it with a foam brush. It applied smoothly and evenly along the seams. There are YouTube videos that will demonstrate how to mix and apply this type sealant. This tube provided more than enough sealant to reseal my tent. I am very happy with the results.

Works Great!
Used this on my deer doghouse blind. Worked GREAT!!! Easy to apply, and once dried, it did NOT crack or come off. Very Flexible! I will continue to use this on other things.

If you tent is leaking at the seams you need this.
My 2 man 2015 tent had starting leaking and I notice that the water drops were coming from the seams of the fly. After checking reviews and you tube videos I purchased a tube of Seam Grip. I used a syringe with small tip to apply it on the seams and then spread it with the little tool the sealer came with. I sealed all the seams on the rain fly of the tent. It worked PERFECT! It dries clear. I now have a tent that I trust again in the rain. Carmen

Easy to work with
I used it for sealling the seams on my 17 years old tent and it worked really well. Because the tent lost all dwr, I applied it also about 5 cm around the seams to waterproof the fabric itself and not only the seams. It seems like it's strengthened the fabric itself where the poles touch the fabric. It is very easy to use. I was using the enclosed brush but it's actually simpler just to use the tube and rub the fabric with it directly. If you only using that for the seams, it is so thin you don't actually see it unless you look really closely. So if you applying on a relatively new tent it will not make it look ugly. It sticks really well. And it dries pretty quickly.

Scouts...can't teach 'em, can't beat 'em either. (Totally kidding here)
Doesn't matter how many times you tell them. Knives don't belong near tents. Neither does fire, but that was a previous lesson. Don't play with your knife around the tent I told them...over and over and over again. Somehow while a scout was teaching another scout how throw his knife during free time (No, no one was hurt miraculously) it bounced up off the stump, did a mid-air turn much like a UFO or a certain "magic bullet" and flew towards the tent. Luckily it climbed in altitude and just skimmed over the rain fly. So they fearing the wrath of the leader getting on their case, didn't tell anyone as it just missed the tent. Well irony is not without a sense of humor it seems. That night while we were all sleeping the heavens opened and it rained. Then it rained harder and harder until morning. It just so happens the two scouts involved in the knife incident were sleeping right underneath the supposed "near miss". They woke up soaked. Through their lack on tying the rain fly out to the trees or stakes, the water would pool and run right into the surgical tear in the tent and rain fly. Lucky for them that was the only day it rained and they got all their stuff dried out. I was ready to right the tent off as a loss as many tents before it. Then a quick search on google turned up this product and an awesome video. I ordered it right away and two days later, thanks to my Prime account, I was ready to play. I used some packing tape to hold the cut together and slathered this on the other side about an 1/8" thick extending beyond each side of the tear by 1/4". I let it dry for 24 hours. Seemed to work nicely. Now for the other side. I removed the packing tape and then repeated the process on the tape side and let it dry for 24 hours. I used a little baby/talcum powder to put on the silicone fix to get rid of the tackiness before I folded up the rain fly. 3 weeks later we used the tent on a campout and it rained on us again. But the fix held well. No leaks in the tent this time. Great product that I'll use a lot now. The SILNET stays flexible and should hold up well to the scouts abuse.

Le silicone sil fonctionne très bien avec la tente cosmitto et la tente mongar 2 je tiens a vous le dire j'ai essayé le gear aid fast cure sur la toile cosmitto et la toile est en polyester et ça n'a pas fonctionné parce qu'il est dit que le silicone sil fonctionne avec le nylon et non le polyester mais le silicone sil a très bien fonctionné sur la toile écaillée sur les coutures de la tente cosmitto j'ai mis par dessus le fast cure écaillée et finalement ça réellement bien fonctionné. Les deux tente sont très bien recouvert sur les coutures intérieure mais pour être sûr que l'eau me tombe pas dessus j'ai mis le silicone sil sur le dessus de mes deux tentes très important pour que ça ne coûte pas trop cher en silicone sil prenez des seringue sur amazon pour en mettre seulement sur les coutures avec un tube et la seringue j'ai fais ma tente mongar 2 de naturehike

This proved useless for fixing cuts in silicone. It does not bind with the silicone, and so didn't serve the purpose I got it for, fixing a leak in a water bladder. However, it's useful for everything else. I've used it to apply a protective coating around a screw under my table that was brushing against my leg, and to add drops to a bag's shoulder handle, making the handle grippier on my shoulder.
