It comes in a full range of basic colors. Dry time and applying layers to poor splices with "pokers" are the only real drawbacks. But pokers also puncture tubes and tape too. The likely hood in the order listed. Layers will fill over a poker so it never rears its ugly head again. Over tape it's a glue to insure against unraveling. I've used it for about 40 years, off-road and professional electronics settings, it's a must. You can expose a wire mid length for a meter probe, and just dot the hole after.
