Soldering is by far my first choice and milticore solder (electronic solder) has cores of resin inside it. One needs to burnish the cable first with fine emery cloth to improve solder flow. Then trim the excess cable afterwards.

Another is to use heatshrink tubing. A hair dryer will do the job nicely and this is an alternative for those that cannot solder.


BTW, if you solder the crimped area of a cable where it was clamped, you can then straighten it out later on as it stretches and you won't see the crimp too much. I have also placed a small blob of solder onto a cable to keep it from slipping in a clamp on some problematic components. The blob can always be melted away.
