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.

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.
