[TowerTalk] [Bulk] Re: Cordless solder irons

Hi Roger,

Do you need penetration? Or would sealing any exposed strands (such as the end of a wire poking out from a crimp) suffice?

Such as: crimp wire to connector, use flooded heat shrink to shroud the insulation and crimp, and something such as liquid tape, RTV or similar sealing the open end of the crimped connector.

The hot melt glue inside the flooded heat shrink tubing would likely penetrate better, but I'd not want to depend on it penetrating to the center providing a moisture barrier.
