I did think your suggestion was rather tongue in cheek but tbh it would be easier to maintain if a wire failed at a later date .
None of these rj45 “ waterproof” sleeves seem good enough - always fail relatively soon I.e in under a year . So I’m going to try this gel crimp solution . First though I need to find a box to put the cables and crimps in . Needs to be bomb proof and water proof . A tug on a cable will easily break those frail cat wires .
