Greetings fellow car buffs. Glad to have found this site. This is my first post.
This past November, I bought a 1968 Dodge Polara 500 as a surprise gift for my wife (exact duplicate of the last car her father owned at the time of his death in '68). I presented it to her on the 40th anniversary of his passing in the same driveway in downtown Ottawa that the original Polara sat in 41 years ago. To say the least, she was a happy gal, and I earned some brownie points for some years to come.

The car was located in Calgary, was (and is) in excellent condition, and was kept in a garage in Calgary its entire life. I placed it in winter storage in a proper enclosed dry space that was lightly heated and will continue to do so each winter. However, now that I have the car at home in Chelsea, I have a problem. This car is long at 221" -- 9" too long to be able to close my garage door. Beyond that, the area I live in is damp (especially right now) and humid a lot of the time, including in the garage even when I (must) keep the door open. I'm going to have to store it outside and I've been searching the web for a suitable exterior portable enclosure. Of course, not just any portable enclosure will do especially since I must keep the car on a non-paved surface -- directly on the ground. There are some enclosures that have bottoms in them, you can drive the car into it, then zip it up, and some even come with "drypacs" to absorb humidity. However, those I've found don't seem suited to the outdoors. I suppose the ideal would involve a concrete pad and a good enclosure, but the only place I have to keep it, I cannot install a concrete pad. I'm wondering if a good base of crushed stone and enclosure would do? If not crushed stone or concrete pad, what might work?
I'm hoping some of you folks with old cars you care about have had to deal with something similar and can give me some advice. It concerns me that I may not be able to properly prevent the car from rusting when it was kept so for so long.
Also, I wouldn't say the car is entirely rust free but nothing actually shows. I don't plan to do a full body off restoration and I've read that if all rust is not removed, rustproofing is of no use. However, would an oil spray/injection at least help?
Advice from anyone in-the-know is greatly appreciated. Thanks.
