Hi Matthew, When I was self-employed I bought some magnetic signs for my car.  I would get more inquiries than anything.  My business didn't go up very much, but it did go up some.  Don't leave them on for months at a time.  Take them off when you wash your car-especially if you go through a car wash!.  Left on too long can damage the paint job on your doors!  (Experience, my man!)  I'm not sure that you would have more liability than having no signs, but that's why we all (should) have libility insurance for our cars.  They are fully deductable as advertising expense, but not the paint damage! Hope this helps.
