Your car will go through a freeze/thaw cycle every time you start it from cold and turn on the heater!
Good air circulation can evaporate the moisture rather quickly, while poor circulation cannot. So, don't store the gun in a plastic bag, let it breathe.
If it is going to sleep in the glove box or center console, take it out once in a while, look it over, wipe it down and take it out to play, or at least tell it that you still love it.
