was useless when it rained and as many times as i what rain three stars 4 windshields and only used half a bottle that worth every penny for safe driving good quality easy to use this was the second one i bought im going classic cars need a classy cover it gets the job disappointed it does not fit perfectly to my toyota corolla 2015 works great i wouldnt recommend it for outside in wet fits over my prius perfectly and easily what a deal it wouldnt store as easy or be as easy to put on it was exactly as described and was easy to put on the car unbeatable for the money
