Somebody told me this was supposed to have some basic water proofing on it... Is that true? I have the generation 2 on my three outdoor cars and over the years I have blown up a couple when I have got a little splash of water on them that I didn't think was actually going to blow them up. A little bit of water resistance would be nice not that I'm splashing through puddles but there's the odd time you find a little bit a water on the day after rain or after the tracks been watered
