 Rick,I have had good luck with black mechanics silicone.  It is not as easy to make it pretty but it is very robust.Hank

 Rick,I don't exactly know!After googling & asking advice I bought a number of glues that were supposed to be good for glueing PVC. I did a number of glueing experiments & found I could peel the glue off thePVC with all products. I went to Lancer inflatables & asked them what theyused on their PVC boats & they sold me unmarked cans of a two pot heat activated PVC adhesive. I think he said it was a 3M product. It was fantastic, the PVC would tear rather than the glue peeling off.Most wire jackets are PVC. I use PVC outside the hull & Teflon coated wireWhich is more fire resistant inside.I looked at some professional rubber through hull fittings I had & saw that theyhad a thin layer of rubber vulcanised to about an inch up the jacket fromwhere the head of the fitting was. I am copying this by coating the through hull& the jacket of the wire with the PVC glue.Doug Jackson did a series of videos on home made through hull fittings wherehe had failure after failure & this lead me to look in to it a bit more deeply.The water under pressure can squeeze between the insulation & wire, & the epoxy it is imbedded in, but with a layer of PVC glue over everything it can't.I had success first test at 2000psi.This looks a good product.https://www.nrs.com/repair/stabond.aspAny product they use on PVC inflatables should be good as it is water resistant as well as developed for PVC.Cheers Alan

Brian,I cover the insulation on the wires & the potting material with a PVC glueup to an inch from where it is potted. I use a 2 pot heat activated PVC gluethat will tear the PVC before it peals off.Reason for this is water can force down between the PVC & the potting material.Alan

 Brian, it the strands are solid core, you can strip off the insulation and then pot.  If the strands are multi wire then cut and sold in a section of solid wire to pot.Hank

 Hi All,            What would be the best way for me to pot a cat5 ethernet cable?    Would the insulation need to be removed?
