Wonder if anyone can recommend a long lasting , waterproof,and durable car cover for a 56 victroria. I have 2 56 victorias  that I have stored outside and have been using expensive $168.00 canvas covers to keep the weather off. They last about 3 years before tearing and molding. I have seen polyester covers advertised but they don't seem to have eyeholes for tie downs and I wonder if they would stand up to outside storage. Any advice would be appreciated.  Hate to see good projects rusting outside.
