I have heard many times that dew will rust out cars....used car dealers
refer to "lot rot" which occurs on cars that just sit on the lot.  The dew
collects but without driving the car and getting ventilation around it it
never really dries out and the next night more dew collects.  As far as the
vehicle getting wet from dew everywhere air can get to, I'm not so
sure.......I believe the dew only collects on vertical surfaces similar to
rain and then runs down the sides, drips past moving window seals etc.  Just
had breakfast outside this AM and the top of my outdoor table was wet with
dew, but underneath it was dry.  The chairs pushed under the table were also
dry so that's my scientific proof!!
