Coghlan's Water-Based Seam Seal

Works well. I have used this with success on nylon tent floor perimeter seams and rainfly seam.  Neither were reinforced with tape and this has lasted over 8 years, 8-16 days, four seasons per year without reapplication. I have just applied to the opposite side of taped seams of a new tent. This works well as it saturates the thread and seals the stitched holes. This comes with a push to open top with brush attached. Application is easy: shake before use, invert, lightly squeeze bottle to saturate… Full review

Gear Aid Seam Grip+WP

Don't waste time or money. Tried repairing the seams on a hood neck shoulders on Goretex Extrem Berghaus Paclite Don't stick well the seams curl up like old corn beef, when applied. When cured it peels off like dead skin. Basically my Berghaus Extrem Paclite Jacket had some seams coming away. After searching and reading reviews, I thought sod it give it a go. When applying seam grip it soaks into the seams, making them curl up, so you have to sit there and keep pushing edges down to stick, best… Full review

Gear Aid Fast Cure Seam Sealant

Got it at REI...was the only thing they had. Applied to tent. Rained next day. NO DIFFERENCE; leaked just the same. Lousy results. REI issued a full refund. Don't bother!! Lousy product; did not work. Full review

Gear Aid Seam Grip+WP

The only thing I will use on cuts, tears, and seams. I've used Seam Grip on everything from tents, to rain shells, to hiking shoes, to even fishing waders. Depending on the location and size of tear, I may back it with Tenacious Tape, then smear on Seam Grip, such as on the sleeve of my rain shell.  On my tent seams, I actually had to re-stitch, then seal it. My largest job was when the vinyl window on the rain fly of my REI tent simply let loose — literally coming off. It took a few evenings… Full review

Gear Aid Tent Sure Tent Floor Sealant

Tested in the Colorado backcountry in "not-so-pleasant" weather. This is a great product that does what it claims.  I would recommend application before each season.  Backpacking gear and clothing is expensive and I'm sure no one wants to get it wet, especially inside your tent. I applied the floor sealant to my Mountain Hardware Light Wedge 3 at the beginning of the season.  Application of the product was easy, it didn't smell too bad, and it dried quickly. I would definitely make sure the… Full review

Gear Aid Seam Grip+WP

There are other products out there which can fix leaking camping gear, although I have tried a few with disappointing results. Then I got McNett’s Seam Grip. There are other products out there which can fix leaking camping gear, although I have tried a few with disappointing results. Then I got McNett’s Seam Grip via Alpine & Leisure, an importer of McNett’s products for the New Zealand market. What I like is that Seam Grip comes with a brush-like applicator head, and a tiny paint brush… Full review

Aquaseal Seam Seal

Used on polyester thread sewn as a deck seam on marine grade vinyl. Tested uncoated sewn sample and water ran through the seams without hesitation. Dried cover and let sit for 24 hours then coated according to instructions. The cured cover held water with only one or two slow drips in the hundreds of stitches. I wouldn't use it to make vinyl fabric buckets but to keep water from reaching the seat foam in boat seats this worked very well. Full review

Coghlan's Seam Seal

I could never find any info regarding this product, so I thought I'd provide my input for any others thinking of using this product. Short and sweet: I would not use this product again, nor recommend it to anyone, unless you were in a complete pinch, could find nothing else, and were unable to mix your own.  I've used this product twice (giving it the benefit of the doubt) on two different tents, each time with the same result. It goes on clear and predominantly dries white. The majority of the… Full review

Gear Aid Seam Grip+SIL

Sil Net is a silicone seam sealer made by McNett outdoors in Bellingham, Washington.  The tube I have is 1.5 oz and comes in a squeeze tube similar to toothpaste.  I first used SilNet to seal the seam on the tarp I use for my hammock. The product comes with a brush that is used to lightly apply the product to the seam. It seems easy enough. However, more is not better! I quickly learned that a little of this product goes a long way. That's good because one tube will last you a long time.  Applying… Full review
