I used one for 6 to 9 months. The slightest breeze and the cover would start wearing the rubber roof at the sides, wear the paint off the metal trim, rub the wax off anything it touched. You also need to use protection on anything that protrudes or has a sharp edge as they will tear holes in the cover. Needless to say the 400. 00 cover has found a home in the shed.
