Hmmm.. hadn't thought of that....The only thing that I don't like about the black stuff is that you can't see if it's corroding underneath.
How do you see if it's corroding underneath heat shrink or butt connectors? The black stuff is actually better than even those because it's more of a moisture seal also.The only thing that I don't like about the black stuff is that you can't see if it's corroding underneath.

You have a couple of things going on that make me believe the liquid tape would be better for the average backyard mech. The first thing in this case is that the wires don't appear to have been severed. The type of connector he's working with only really cuts through the insulation more or less. So you shouldn't be dealing with a soldered connection etc. Heatshrink wouldn't work unless you had pretty small blade and were able to get them out of the connector down stream. You might be working with aircraft grade heat shrink, but not everyone has that. A lot of times the cheaper heat shrinks don't seal as well.I'm not sure what makes you think that black silicon is a better moisture barrier than any other. Silicon sealants are generally categorized into temperature range and chemical resistance. From the Permatex Website:
I don't use butt connectors and if heat shrink is installed correctly, it's water and fuel tight. I've removed shrink from aircraft that were built before I was born, revealing wire that is as shiny the day it was produced.

To be honest, I always use decent heatshrink
Not to get into all the details of heat shrink, but there are different grades. Some are stiffer than others. Some shrink more or less depending on the job they're intended for. Either way, I still don't see how you can see corrosion under any heat shrink.Autozone has it in kits (usually). It's not special with maybe the exception of the stuff meant to be exposed to sun.
