I don't drive mine in these conditions. Not to say that you shouldn't or can't, just a choice.
Many folks drive theirs all year. If you haven't done so already, I would advise that you check the 'rust' thread and check your car in those areas. You may already have rust and not know it.

For my daily drivers, I try to take them through a touchless car wash with undercarriage spray at least every other week during the winter months.
