This cover should only be put on a PERFECTLY CLEAN CAR. It should be kept clean itself and replaced every 1-2 years. It should only be put on when you know you have highway miles to travel. I can tell you from personal experience that these covers when over used and not kept PERFECTLY clean can do major damage to the paint. But when used seldom (for long trips) and kept clean, they are great. I will look into getting one for long trips!
