[Elecraft] OT: sorta- Sugru for potting and making custom "lumpy cables"

[Doug Faunt N6TQS +1-510-717-1197]

I want to make some custom cable sets for my KX3, K3, etc, etc.
I like the idea of potting connectors on cables (first did it repairing 
Navy aircraft in the late 60's).
It looks as if sugru will do a good job of this, is readily available 
and not particularly messy.
Have people here tried this?  Did it work well?
thanks, doug
