If you're not yet in the know about gaffers tape, well youre missing out. As a prepping item, its invaluable.

Created in ww2 to waterproof ammo cans crossing the channel into France, its a durable cloth based tape that you can easily tear into equal width strips, sticks to almost anything, and doesn't leave any residue after removal.

I keep old credit cards lashed with about 30 feet of it in every backpack, and every vehicle gets a roll of it instead of duct tape.

Taping up windows after a storm, don't have to worry about peeling varnish or paint off trim or ruining walls. Taping up a busted car window, or a rear tail light that got knocked loose, I've done both.

Ive used white gaffers tape to hide cables behind tvs, black to tape down carpets to tile when elderly relatives visit. You can patch vinyl seats with it, patch up ripped gear with it, waterproof things with it, basically everything duct tape can do, you can also do with gaffers tape, but usually better. Ive even made bandages with it and gauze pads for larger wounds at work.

I will admit that Gorilla tape is superior to gaffers tape for patching things up and needing them to stay patched up longer without repairs.

In a GWOT type situation, you can tape off Scopes or lenses since its a matte tape, without having all that gunk residue stick if you need to remove it later. Ive used it with a strip of pipe insulation to run power cords out my window during outages, with no air leaks. You can seal up whole rooms or windows with plastic in the winter to stay warmer. You can tape sleeves and ankles down, straps on your gear down, slings to your rifles, and since it peels off itself easily and re attaches you can make adjustments later easily
