Did someone tried to sleeve the cables but using just the thermal ends? I mean, not the sleeving and then the thermal stuff to grab it to the ends of the wire, just all the wire with material used at the ends.
I hope to be clear enough, because I don't know how do you call the thermal material to grb the sleeve to the wires.

I want to try that on some cables.
So if someone has done it, would be nice to be seen.
