Hi Donald,
I’ve also had some good experiences using conformal coating to weather-proof parts: https://core-electronics.com.au/catalogsearch/result/?order=bestsellers&q=conformal+coating
I couldn’t find the video, but someone compared a few methods of waterproofing, heatshrink and hot-glue. conformal coating, and some other methods - I’ll see if I can find it!
