Answer 1

Water proofing (And, honestly, it shouldn’t be called this in most cases. It’s mostly water resistance) is just a bunch of manufacturing techniques to try to make it harder for water to travel to core components that would fail in water. You can do this in a lot of different ways, like making it so water has to travel a bit or limiting the amount of space between materials. You can use use things like glue and rubber seals.
