yeah the OEM (snuggest fit i could find) one is really good, left it on my car for about 2 months while i was away (outdoors), like taibanl said its not waterproof, but its breathable so your car will actually dry faster with it on, excellent UV protection and it will not come off with winds (florida tropical storm tested), also great to use in garage to keep the dust off after a detail to allow sealants to cure in case you want a 2nd coat of it.(to avoid rewashing).
