Protecting Tapped Wires?

[ViperTony]

I may be over-thinking this but I recently uninstalled my Vec3 which, during installation, required tapping and/or splicing into various wires and connectors along the harness. On some the connections, I used the quick connect taps and for the ones along the PCM I soldered into the wires. After removing and cleaning up the splices/taps, I was going to cover up the tapped part of the wires with some heat shrink tubing. Is this sufficient? Anything better than heat shrink tubing? I was going to use this heat shrink tubing with the EMI/RFI shielding inside. TIA.

There is a liquid rubber that I've used with good effect. Comes in a can with a brush and also in a tube.

Use a needle to push down the barb of the plug inside the connector, pull plug out of said connector, shove a small piece of shrinking tube over the wire, grab a lighter and put a light underneath said tube, push plug back into connector, push connector back into place and you're done.
Dunnit a couple of times already on my own car and just yesterday on one of the buses at work, does require some finnicking but it works! Either that or get some self-vulcanising electrical tape if you're not up for needles.

Thanks guys. I'm going to stick with the EMI/RFI shielded, heat shrink tubing. I've removed the pinouts so its pretty easy to slide a piece of tubing over the wire and use a heat gun to shrink it.

Heat gun? A cigarette lighter makes shorter work of it if you keep the heat shrink tubing directly into the flame

...yeah, but it also melts the sheathing around the surrounding wires in the loom. Think tight spaces, lots of wires bundled together. With a heat gun, not only can I control how much heat I want to use but I can use various-sized nozzles to control where the heat is going, more importantly not scorch the tubing or wires.
