I do get what you are saying. Water content will eventually equalize to the long-term average relative humidity. Even a thick epoxy casing cannot prevent changes to moisture content of wood that is encapsulated within. But if the inside of the hull is kept dry, then the wood will never get moist enough to rot. | |

The aim is to provide a void free layer over the surface of the conductors AND to use a low water solubility compound. THEN what gets to the surface is water vapour (no voids for liquid, minimal dissolved water as liquid). This slows reaction rate down according to liquid:vapour concentration ratio (500-1000 :1) and water solubility (say 1000:1 at 0.1%. || Typical glass / EVA/ Silicon cell / Tedlar laminated solar panels equalise external:internal water levels in weeks to months. | |

| Jun 27, 2018 at 0:23 | comment | added | Graham | Heat shrink is not waterproof though. It's pretty good, but moisture will make its way up the heat shrink by capillary action; and then the heat shrink keeps the water in instead of out. It might slow the onset of corrosion, but it won't stop it. | |
