I need some small/cheap waterproof junction boxes for some 12v garden lighting. I am considering using little (25mm x 25mm x 15mm) potting boxes and after soldering the wires, then filling the potting box with hot melt glue.
However I am not sure how good hot melt glue is at protecting against water? I understand glue sticks are typically a thermoplastic - so should be waterproof?
The best information I can find in a datasheet is "Water Resistance: Good": http://www.farnell.com/datasheets/1504158.pdf
