Unfortunately I didn't search here before buying the Autotecnica Ultimate Hail Protection cover.
Are they kidding? It's so ridged you need at least 2, if not 4 people to put it on without scratching the car to buggery. Fortunately I opened the cover in my house before trying on my new car. Unfortunately it took me 2 or 3 hours to (sort of) fold it to get it to go back in its bag so I can resell it. Anyone want to buy one?
