[quote=steve70]How about a disposable plastic cover over your regular cover to keep any rain/snow off the car.

I've done that with a project car and it worked fine.

What ever you do make sure the car cover is snug and won't slide around in the wind as it can rub thru the tops of fenders on cars with old or thin paint. You could always put some strips of the blue painters tape on the top edges to help protect it and then remove them later.
