Electrical tape is great for sealing exposed electrical connections. For anything else, it's next to worthless.
The problem with electrical tape' is the garbage adhesive usually used. So the tape sticky part turns all gooey after a few years.I know what you mean and if that's what happens to you, then you are using the product incorrectly. Electrical tape is meant to be tightly stretched against itself. When used that way, that gooey adhesive fuses with the tape, creating a very tight, sealed connection.
