I own a '68 Dodge Polara 500 that's in real nice original condition that I had shipped from Calgary last fall. Unfortunately, the car is just a bit too long to be able to close my garage door. So, for spring/summer/fall outdoor storage (it'll be in proper indoor winter storage), I've had it Krown rustproofed (and will each season) and I'm about to create an outdoor surface with a sub-vapour barrier covered with aggregate to prevent humidity/rust. Perhaps you folks have had experience with various outdoor car shelters. Any advice and suggestions for specific makes/models? Thanks.
