Before applying a bra, it’s important that your coat of paint is in perfect condition. Also, the entire surface of the car that will be covered must be clean. The best method is hand washing. If there is any dirt or scratches in the paint, the clear bra will not lay in a proper manner. For removing any excess water after drying, you can use compressed air. Installation is easier if the mirrors and handles on the doors are taken away. It is important to measure the space to be covered in order you will be able to get the appropriate size roll.
