Wouldn't be my first choice. In a pinch sure but given the drying time required not really practical for multiple joints or quick repairs on the fly as you end up with black shit getting all over the place. In the electrical field it's very old school. Used to use it on underground hand spices. Everything compression crimp and is cold shrink now and so much faster.

Had an outboard that squirrels for into over winter and chewed up many wires. Repaired them all, even plug wires, with it and used motor for years.

Yes that would be one situation it would be worth dealing with the potential mess.

No mess really, but you have to build it up in several layers. I had shrink tubing and marine shrink tubing on hand too but I would have had to cut the plugs off the wires to get it on. So the liquid was well worth the time to apply several coats.

I used to use it under the non adhesive heat shrink tubing. I don't use it much now except for when insulation gets removed from a wire as stated above.

I learned about this while watching Motor Week on PBS. Would you use this on your wire connections? Most all of my wire connections are done with terminal blocks. Might be over kill but could put liquid tape over heat shrink to keep moisture out?

Terminal block(s), Yes!
Liquid tape , fugetaboutit!

I always prefer using a terminal block and captive spade connectors with a lexan cover over the terminal block.

I use heat shrink connectors. I have the liquid tape and have used it once, on some micro connections. It seems to be keeping the moisture out but looks terrible. I suppose you get better at applying it if you use it a few times. I am glad I have it in “the tool box” as an option, but I do not plan to use liquid tape in lieu of heat shrink connectors.

I use heat shrink connectors. Amazon has them at a good price. Main thing is when you crimp that you don’t damage heat shrink and to to over heat them. I use hundreds of them a week at work on patrol boats with zero issues.
