We use dual wall heat-shrink on boats all of the time. Not sure of what the NEC allows, I'm sure that it's archaic.

I just clip on the covers, but there's no reason why you can't heat shrink. You'd have to do 2 or 3 layers of heat shrink, or do one layer of that really thick stuff. The insulation has to be equivalent to the conductor's insulation, so that's a pretty good measure of how thick you need to build up.

Yes, there is a heat-shrink tape. Unfortunately, it's been several years since I had occasion to source/use it, and the cobwebs aren't letting the name through.

Anyone?

For what you're asking for, I think I'd use "Linerless rubber splicing compound" or that paint-on electrical tape that 3M makes.
