I was reminded of this video today when I got caught in thick rain a couple of times.
So, "if you dread the wet don't fret." (I should sell them this as a tagline!) Just waterproof everything with this unbelievable spray. They even tried it on an iPhone (in another video) and it even got a call underwater! I would definitely coat my whole car: inside-out and I also have a couple of pairs of shoes which could use a good coating.
