A car cover is a sensible precaution for the protection of your vehicle's paintwork, but it is important to choose the right cover for your car. You can read our guide to car covers on the Honest John Kit website here: kit.honestjohn.co.uk/top-tens/top-10-car-covers/ and there are covers available that have a cotton lining to avoid scratching the paintwork. It is also important to consider that the car needs to be clean when using the cover, as trapping dirt and moisture beneath the cover can cause more harm than leaving it exposed to the elements.
