Winter storage tips wanted

[jw@mail09.mitre.org (Joe Whalley)]

I have to store my Spitfire outside in Massachusetts this winter. This is the
first year I've owned it. I have a cotton car cover that I thought I'd put on,
then cover it with a poly top, and store the car under a deck. Should I do
anything special with the engine? Bring the battery in? Should the gas tank be
filled, and have some fuel stabilizer added? Should I start the car
occasionally? Anything special I should do when bringing it out next spring?

Thanks
Joe
