Mine stays in the garage over night and is driven during the day, rain or no rain. I wash about once a week and wax about every other month. I take the old wax off about every 3 months or so and start fresh. For myself, my vettes will never be collector items, they will be driven and enjoyed by me, restored as I own them, but driven and never perfect for show. I am a one man parade everywhere I go and the public loves to watch.
Not knocking anyone who wants a showroom car, it is just that showroom is not for me. The happiness of driving these cars is a better feeling than having a perfect car.
Wash it and relax, rust will happen naturally even if you vacuum seal it. Yes the water helps, but is not the only helper of rust.
That being said, water does not have to be introduced into the system for rust to occur. It is the meeting of two dissimilar metals that causes corrosion. This can even happen in free air because of elements in the air. Cathotic protection could be a solution, but the battery would have to be diconnected everytime you hooked up the cathodic protection. How cathodic protection works, a small voltage (very small, small, small, and even smaller) is introduced into the metalic system being protected. The particulars can be found and searched on the web. Ships use this technology and oil platforms in the Gulf of Mexico use it too.
But really this would be over kill, it would cost less allowing the rust to happen, cleaning the areas of concern or replacing those rusted parts if need be. I am sure owners of really old collector cars have better solutions, maybe you can find a forum for model Ts or rare turn of the century race cars. Good luck.
