Regarding heat shrinking...when you have a worn spot like this, where presumably it would be hard to disconnect/desolder everything, slide on the shrink, and reconnect/resolder...how do you put the shrink on? Can you slice the shrink, wrap it around, and then heat it?
I have one spot that is in a very tough to access location. As of now, it is has electrical tape around it, but I would love to get shrink around it.
