Liquid electrical tape
We could find any number of uses for this stuff. We like to fool around with 12V lighting around the house (we have decided to leave the 230V stuff to the electricians), and with some of this we would be set to go. Imagine being able to fix a damaged section without cutting the cable. This goo is waterproof and remains flexible after drying. It would work in the car, boat, trailer and even the caravan if we had any of these RVs.
