Personally I don't use anti-freeze, I simply drain the radiator when leaving the car in the winter months.
I do think there's a good case for using a corrosion inhibitor. Penrite make one specifically for vintage vehicles, though I'd warn that it attacks enamel paint.
If you drive an open Seven you may be familiar with the spray of coolant in your eyes first time you touch the brakes? If so I suggest reading the toxicity datasheet carefully.
