I completed a room remodel, and was ready to reinstall some multi-media speakers. Their wires were unattractive, as they were covered with paint. I used some shrink sleeves to encase the wires. Shrink sleeves are tubes that will shrink when a little heat is applied (gently from a butane torch). The photos below show the process. A little extra time effort leads to a good looking final result.
Original speaker wires covered with paint.
The exposed stranded wire is easy to unravel.
Tinning the exposed ends of the wires to keep them secure.

A nice neat finished wire.
The competed job, a tidy installation.
