Hi Me again, I am having so much bad luck today!! Now I found out in addition to the rattling door, that the bottom undercarriage of my car has scrapes and one of the plastic hooky things that keeps the protective plastic cover is coming off a little. Can or should I say is there any protective spray that can fix the scratches caused by this? I was at my friend's house and as my wife was backing out, she ran over a rock that gouged some scratches into the bottom part of the car! This really sucks!
