I found some "Liquid Tape" made by Gardner Bender at Lowe's that works great for covering these small cables. It is a pain to put on with the built in brush as it was obviously designed for applying to lager cables, but a little paint brush or something like that works fine. Turns out neater than using electrical tape in some cases like the little solders of the insulated cables in this cable. I'm sure there are other brands of this stuff so just look around. It's worth having on your workbench.
