Ok, the silicon spray arrived.

I've had the cable soaking for about 4 hours then removed the glad wrap, drying off any excess with some paper to test it.
I can tell it's definitely soaking in because the silicon spray is disappearing from inside the (air tight) glad wrap, I've needed to open it a few times to add more, it's also best if you pat it down occasionally with your fingers moving it around, also once soaked in a little bend the cable slightly back and forth to stretch the paws in the rubber. Best of all it's making the cable incredibly soft and shiny. Running the cable through my fingers is definitely flexing easier though I'm going to put it back in for a few hours.
Also, don't be fooled when first spraying it on, as the spray comes out freezing cold stiffening the cable until returning back to room temperature.
The most important thing to remember here is how permanent the fix is, so I'll monitor it closely.
Though it IS WORKING.
