      I think I just ruined two tents...

      I used this product on two aging tents I have in an effort to get a little more life out of them. In hindsight I should have stated with one first to see how it did. I applied it to the interior tent floor and the underside of the rainfly. I then applied the water proofing spray to the outside. I let them dry in my garage for a week. and then hung them on hangers for storage till my next trip. On my trip when I pulled the tent and fly from the stuff sack (that had been stuffed for less than 24 hrs) the fabrics had completely adhered together and took the better part of a half an hour to unstick them. The floor of the tent was extremely sticky. That night it rained and I had to pack up the tent wet. The next afternoon when I took the tent out to dry it was a complete glued ball. The moisture seemed to amplify the stickiness. I followed the directions to the "T" and invested upwards of $80 to fully waterproof both tents only to have them ruined. Don't use this product unless you want a glue ball for a tent.

      Do not buy

      Impossible to apply. Do not buy this product. Your money is much better spent applied to a new whatever you are trying to repair. Came here from MSR under recommendation. Very unhappy with purchase.

      Thanks!!! used on two different tents last year. Tested both in the rain and stayed bone dry. Highly recommend. The rainflies were peeling and water was starting to seep through. Haven't had any issues since applying the tent sure.

      Better than expected

      I was hesitant buying this reading the review but when I put it on is as smooth as the original finish. It seemd to soak in much better as a matter of fact. I covered a 2 man REI half dome tent fly. Getting the old finish off was a pain but the product is easy to use. Seems good so far.

      Attempts to re-seal Hubba2 NX tent floor failed miserably

      Having learned from my experience to spend a lot of time and effort on mixing the Tent Sealant (see previous review with same title), I did buy another bottle of Tent Sure Tent Sealant and applied another coating on the inside of the Hubba2 NX tent floor. Unfortunately the tent floor is still leaking. I have no option but to conclude that the Tent Sure Tent Sealant does not deliver on its promises, it simply does not seem to work.
