Heat-shrink - HO scale

When one has a plethora of soldered wires loosely and chaotically clustered together beneath one's baseboard, one is advised to cover the bare soldered ends with heat-shrink. If a pair of bare metal ends were to touch then a short-circuit would occur and blow (ie destroy) the DCC microchip in the locomotives.

Heat-shrink is basically rubber tubing which one cuts to size and slips over any bare wire. One then applies a hairdryer and after a few minutes the heat-shrink melts and forms a permanent insulation over the wires.

Aforementioned plethora.
