I've seen this advertised a few places, and even know where I can find it on the 'net, but i've never seen it sold locally... Mind you I haven't been looking *really* hard, just trying to remember to keep my eyes open when I go into places like Home Depot, KMS Tools, etc. Here's the McMaster page for it.
The tape in question is either silicone- or EPR-based (Ethylene-Propylene-Rubber), and has no adhesive. But the tape sticks to itself, and forms a permanent, non-removable joint (with itself) within a few seconds. You can use it like electrical tape, but it will never slowly creep over time and leave you with sticky residue all over the place. Good for covering electrical joints that will be left out in the weather, oh, say, like those on a motorcycle. Or joints on air hoses. Or battery terminals.
Has anyone seen any or know where it can be bought easily?
