My Evolution cover (purchased through Amazon, but not from Car Cover World)left a horrible grey film on my car during the first use. The manufacturer said the cover just needed to be washed first. The instruction sheet they send with the cover says it can only be washed in a non-agitating commercial machine and then must be dried on the car! And, washing the cover may reduce its protective qualities!! A cover that needs to be washed before it can be used--and may be damaged in the washing process--is, in my opinion, a poorly made and defective product.
