Great stuff

I've used Seam Grip for years and it's great stuff. Cramponned your climbing/skiing salopettes? Then seal the tear with SeamGrip. Has part of your coat become worn or torn? SeamGrip it. The tape on the seams of my original 25yr old goretex jacket had started to come adrift, so I SeamGripped every seam and the tape was re-stuck. Result? The seams don't leak anymore; so my jackets is weatherproof again. Bigger cuts etc can be covered with Tenacious Tape and I seal the edges of the tape so that the don't come adrift.
My friend's mountaineering jacket is covered with the stuff and it goes on and on. Seam Grip is brilliant.

I had to seal areas on a Hennessy hexagonal tarpaulin (70D nylon with a PolyUrethane coating). I had made a few modifications to it.

This product is excellent !

It sealed perfectly, stayed very flexible when it had cured and it has not de-laminated from the nylon tarpaulin (unlike other products I have tried).

Well done dudes !

Not for silnylon!

Excellent product, but it does NOT work with "all natural and synthetic fabrics" as stated.

The small print on the pack states, "Not suitable for use on Sil-nylon (silicon based) tent fabrics". Since most tents are made of silnylon nowadays, you'll need to look for a product called Silnet, also made by McNett, but not stocked by Go Outdoors (at the time of writing).
