I have a 84 se which i drive every couple of weeks. What is the best way to prevent rust? I'm planning on putting it in storage a few months and I'm considering a "carcoon" bubble with fans to keep airflow around the car. I thought I read in hemmings or someplace about any electronic device which clamps to any metallic area on the car and "charges" it at a low frequency to prevent rust. Anyone hear of such a thing or would a dehumidifier in the garage get the same results.

thanks
