I think that the adhesive inside of the adhesive-lined heatshrink IS a type of hot-melt glue. I know that it can be reflowed by applying heat. So, it makes sense that adding additional hot melt would allow you to make a watertight seal, although I'm not 100% sure that hot melt glue is completely waterproof and doesn't absorb water eventually.

Basically, i'm going to have three audio cables (2, 3, and 4 conductors) connected to each other at central location (possibly with a resistor or two between some of the wires). Rather than use a junction box, I was thinking of just potting it. Has anyone done something like this before? I'll need to select a potting material, and figure out something to use for a mold. Any suggestions? Anything else I am overlooking? Does the cable jacket material affect the selection of the potting material? >>> >>> >>> >> -- >> http://www.piclist.com PIC/SX FAQ & list archive >> View/change your membership options at >> http://mailman.mit.edu/mailman/listinfo/piclist >> > > > > -- > KPL > > -- > http://www.piclist.com PIC/SX FAQ & list archive > View/change your membership options at > http://mailman.mit.edu/mailman/listinfo/piclist > -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
