I drove my car on it and took battery out then put the dry packs in and zipped it up . Really nice to have the car in where it will be dust free all winter . The only minor problem was I should have had my wife help zipping it up , need 3 hands . I got it though and it is great . I bought 2 of them , the other car will be in the second one pretty soon . Great product . Thanks
Pros: Dust and moisture free .
