Do you really need body side moldings? Most think of the strips that run from front to back over the doors as protectors. Some think of them as decoration. Many think of them as both. The weather-proof flexible moldings are capable of absorbing the force of another car door or similar object and preventing damage to paint and metal.
Parking lots are a notorious location for collecting chipped paint and dings from others opening doors into your doors. Also a great place for you or your child to discover a light post or other unmovable object within the opening swing of your own door.
Depending on the height or shape of what hits your door the moldings will not eliminate all dings, but they can prevent a majority of them. In addition to the protection from damage they can complement the looks of your vehicle.
