I have been storing cars for the winter for over 30 years. Just park it and forget it and start it in the spring. No problems ever with any car I ever had. They have been stored both indoors and out. How long do you think cars sit on a car lot sometimes before a buyer comes along?

Lots of great suggestions here. I guess if anybody would know, take SPAD's advise. I Imagine if you survive a winter in Finland, you know what to do. On all this battery stuff, just take the thing out and bring it in the house. Give it a charge before installing next year, and your good to go.The car may run a little weard till the computer straightens out, so just be paitent and take her for good ride. Remember,DO NOT store the battery on concrete! Definately spray the undercarrage. I use WD-40. I like the furnature wax idea.
"Vunda", thanks a million for your service time in Iraq, God Bless you for that ! I also like your picture of Dexter. I dig science, string theory anyone?

Does anyone go to say a Penzoil place and get their underbody professionally sprayed?
