Adhesive lined heat shrink tubing "versus" liquid tape?
Totally different products for totally different applications. Boiled down it amounts to "this" in real life...
When a pinprick hole is made in a wire insulation to test for voltage, the pinprick can be effectively sealed environmentally and leakage wise by dabbing on a bit of the acrylic sealant. Packard-type OEM sockets and plugs that pass 10 amperes or more of current are especially susceptible to failure. This is why most newer vehicle pass wire harnesses straight through a firewall without using a junction or terminals at the firewall barrier.
Someone wants me to find out why their slide out does not slide. Within 15 seconds or so I find one of the terminals affixed to the motor is not affixed to the copper strands inside the terminal. I have a toad that "had" an instrument panel power problem. I found the negative wire terminal that attached to the instrument panel edge card connection was leaning on its shovel. Power at the edge card, but not continuing on to negative. I wanted to know WHERE the problem was. EXACTLY. The edge card connector to wire connection was bad. Without piercing insulation I would still be scratching my ***.
I still have a Plumb chisel to scrape through frame gunk, and 90 grit emery to sand through corrosion.
BY THE WAY. I have informed (I forgot how many) electrician mechanics to make up a MAGNET with a hook-to-point to make your own ground attachment point on a flat ferrous surface. Scrape. Clank. Connect. Ground.
BTW a particular brand and type of heat shrink tubing is so far superior to "#2" that it's a joke. Sold by ICO RALLY the "HIM" 3 to 1 shrink tubing is as far as I am concerned the Rolls Royce of shrink tubing. The meltable adhesive liner is freakin' strong. And the tubing itself is HARDER to cut (damage) than even cross link poly-olefin wire. ICO RALLY HIM is remarkable stuff. The company is in Palo Alto, California.
