You never know if and or what petroleum products/additives and other stuff are in some glues,
which may or may not affect the cables.
Not sure how well gobs of hot glue would work and hold up, may even burn the cable
A 'simple' and quicker cable fav of mine that won't break the wallet too much is a few turns of good electrical tape at 50cm to 1 meter intervals (or whatever 'feels' right and behaves)
and cable tie on top of each tape up,
that once tightened gets a flush cut with sharp cutters, so no bits sticking out from the cable tie.
If the cable tie is long enough, you can try doing two turns with it for more grip and less of a single point tight spot
The tape is also a good buffer to keep the cable ties from cutting in to the cable in case of a disaster
It's a bit cumbersome and a bumpy ride on bare hands when rolling the lot up, but serves well enough and should last a long time and dragging around abuse
BTW Keep some spare tape and cable ties for repairs if any ever break off or get brittle with age and weather exposure.
FWIW: I use this method when I need a 'do it once and never think again' cable loom of dual or multiple cables.
and my custom made 7 meter real deal booster cables are done this way
Plastic/nylon adjustable garden hose clips are another option worth a look at too
Good luck mate
