When I have a really nice car with the paint polished to show quality, I only cover it when it is completely clean, as dust on the car results in microscratches even when indoors (just from putting the cover on/off).
If the paint isn't all that great, I still only cover it when the car is clean enough that I can "California Duster" it. Again, this and the above are only indoors.
The only time I see it fit to cover a car outdoors is when rain and snow stand to do more damage than sun and wind. In this case, it has to be a water proof and sun blocking cover, or it is pointless. And I would still make sure the cover comes off regularly (ever 2 weeks, perhaps) and the car warmed up and allowed to dry out any moisture that got trapped under the cover. And once again -- especially because it's outdoors -- I'd make sure the car and inside of cover are both perfectly clean before putting cover on car (because of wind/scratching damage).
