Rated 5 out of 5 by from The description and spec are right on I only used this to seal the seams of an older REI half dome tent I have. Like the description indicated, it really was just enough to seal the bottom seam around my tent and the seams of the rain fly. I was impressed with how it dried to a rubbery and pliable finish. One tip I have is be sure to use the hand brush that comes with it and not the screw on brush head. It takes a bit of time to squeeze the sealant onto the brush and brush it on a section at a time, but it is worth it for the results. The only negative is that it is messy and difficult to clean up the residue that gets on your fingers - I had to use paint thinner.

Rated 5 out of 5 by from Messy? Yes. Good stuff? Definitely. This sealer works and wears well. I've used different sealers over the past 25 years and they're all messy. Just do it...or get wet. Having to re-seal the seams is a necessary evil of using your gear for a long time. As noted by others, it WILL stick to itself. The longer it can cure, the better. I re-seal in the fall and let the gear sit in my garage attic over the winter unpacked. If you must pack your gear before it's fully cured and are worried about it sticking to itself, go with the tried and true method that was handed down to me through Scouting. Let it cure as long as you can, then lightly dust the new sealer with talcum powder. Yes, the seams will stand out as white lines, but they won't stick. The white will fade as the talcum wears off anyway.

Rated 4 out of 5 by from Failing Boot Soles Completed the Trip! I've carried a gear repair kit for hundreds of miles of hiking. The kit doesn't weigh much but before each trip I'd look at the kit, with the Seam Seal and question the weight. Half way into a recent Desolation trip, miles from a road on our third night out, we reached camp and on checking my boots, I noticed the soles coming loose! Not now! I'm miles from help! I didn't panic but I did pull out the Seam Seal. Following instructions I glued each boot sole and clamped them with rocks. Crossing my fingers I waited. The next day, viola! Boot soles are intact. Causiously I proceeded on the trip, checking the boots. The soles held to the end and I no longer question the added weight of this item. I now don't leave home without it.

Rated 5 out of 5 by from If you are a camper then you need this on hand. I used Seam Grip on all four web loops were they are sewed to the fabric of the tent. I did this 7 years ago & it still on the web with no leaks. I also fixed my self inflated mattress when the edge came apart. That was 5 years ago. Still is going strong. Got a new tent & I did the same as old tent & I have been in at least 4 nights of pouring rain with my inside dry. I go out of town every other week & sometimes back to back. I stay at state parks instead of hotels. All year round.

Rated 3 out of 5 by from Tube is too small for a 2-person tent. My only gripe is that a 1oz tube is NOT anywhere near enough for the average two-person tent AND fly. I thought I was being sparing, but ran out a foot short while sealing the fly on an old North Face Tadpole. Didn't even make it to the tent floor. If you have anything but the most basic 2-person department store tent, one tube isn't likely to be enough. I'd still recommend it, but it's irritating having to make a second trip to the store in the middle of a project and ultimately end up spending $30+ on gas and product just to seal a tent.

Rated 5 out of 5 by from Trip and Gear Saver! This is an essential item anytime I go anywhere. The McNett brand is much better than most on the market, and is great in a bind. Its saved me during recent rainstorm/snowfall in Yosemite when our backpacking tent leaked,(patched and dried in VERY wet conditions in less than 30 mins)mended a torn sole on a hiking trip, and a trekker mattress pad that had a small tear. Its one of those never go without/can use anywhere items.

Rated 5 out of 5 by from Repairs Everything I was thru-hiking and halfway through I blew out the rear seam of my pants. I tried sewing it and it immediately broke. As a desperation measure I put seam grip along the pants material. Worked perfectly! Completely sealed! Throw out your needle and thread!

Rated 5 out of 5 by from Works Great No issues with this product at all! Like everything else in life, it's all in the prep. I had a 10 year old tent whose seam tape was pulling off. Removed the tape, wiped seam with alcohol, put masking tape on both sides of seam, squeezed out the sealer and used a $.50 paint brush to smear it over the seam. Dried in 2 hours , removed the masking tape and left tent up overnight. the next morning it was dry, no tackiness at all. Great product!

Cured for days, still tacky. Seam stuck to itself; despite being careful, some Grip peeled off, had to re-apply. Q: instructions say use talcum powder. Everything has scent. Do I want to smear bear attractant all over my tent? Paranoid? Wears off?

Can this be used to seal the inside seams of a yeti hopper soft sided cooler?

Asked by: Ranger24
The YETI Hopper's are RF welded - the process of bonding together materials through the use of electromagnetic energy, which results with a weld that is completed by applying pressure to the bonded area and ensuring a successful seal. ​The YETI Hopper is leak proof with the RF welding technology and therefore does not require an additional sealant.

Can this sealer be used in situations that require some strength? The window on the rain fly on our Cirque ASL 2 tent came unglued, and I think it was partly because the fly is under tension. If not, what glue is recommended to glue the window?

I sealed seams on a pop up trailer and inadvertently got some of the seam sealer on the zipper teeth.  What is the best method of clearing the cured sealer from the teeth of the zipper so that I may open the zippers?

Asked by: Mc52
The challenge with Seam Grip is that once it hardens it is designed to be permanent. McNett recommends taking a pair of tweezers and razor blade and try to carefully dig out the Seam Grip.
