Re: [TowerTalk] Weatherproof Sealant

[Red <RedHaines@centurytel.net>]

Greetings, TTs;

In my former life as an engineer, it was agreed that keeping water out 
of enclosures was difficult.  When possible, we designed enclosures with 
drainage and ventilation (and screening to keep out the critters).  True 
sealing to keep out water vapor required materials like glass and solid 
metal;  materials like rubber just slow the migration of water.  I 
worked on one undersea system.  The approach employed was to enclose 
electronics in the top of an oversized box, with enough empty space in 
the bottom to accommodate several years of water entry before the 
accumulating water reached the electronics.

There are other approaches, but these were among the simplest and most 
reliable.
