It is often specified for use in places where a heat gun would be inconvenient or dangerous like when working in or around fuel tanks or the like.

I have only ever tried out samples of it given to me by salesman types, but it is pretty cool stuff. Expensive if I recall correctly but I guess it makes sense if you have an application that needs it.

We used it at work on our communications towers on the mountain tops. I retired 16 years ago so it has been around for awhile.. Do NOT put you finger in and pull the strap out LOL...

Yeah, it was quite a few years ago when I was introduced to this stuff. I have not had any reason to look into it since but I'm guessing it is still pricey.

Funny what you say about not putting your finger in it as one of my coworkers did just that with one of the samples, trying to be funny. He made a bit of a mess of his finger trying to cut the stuff off. The grip was tenacious and the material was tough to cut without cutting the finger underneath it. Not one of his brighter moves!
