Hey guys I have a 2007 335i Coupe and Iím taking a road trip this spring and want to take my baby but don't want to get a [Oops!] load of rock chips on the front of the car and the mirrors. I have heard about the clear protectant shield like thing that covers the fascia of the car? Does anyone have any input on this or any other thing that would help that you can't see? And where to buy them at?
