Mystery black goop.. what is it and where to get some?

I think I remember a cable guy used it for sealing underground splices they made, so see if you can talk to one of them if you see one.

Oh yeah! I never put the two together, but this might also be the same stuff -- or at least similar stuff: http://www.coaxseal.com/. It comes in a much smaller roll than the stuff pictured above, but otherwise seems identical. It is a stretchy, sort of sticky rubbery goo, separated on a roll by paper. You can mold it around anything, but it remains stupidly sticky and will get on everything and pick up every piece of dirt it gets near.
