Today I was informed by my parents that I am going to start to have to keep my car outside because my dad just bought a new car and understandably it is going to be the car taking up the spare space in our garage. I have been told if you don't keep your BMW garage kept, it will lose its clear coat and lose its shininess etc. So my question is what should I do to keep this from happening now that my car has to be kept outside always? My car is a titanium silver E46
