I just recieved a call today from a woman wanting me to detail her Suburban. She explained to me she has a "orange film" all over the vehicle as a result of water damage. I explained to her that I would have to examine the vehicle first to give her a fair estimate, problem is I have never run into this type of damage and I`m not sure if I can help. Based on what she has told me the orange film caused by water points to rust, but could be more of a yellow color which would indicate to me hard water i.e. sulfur. Any guess on what it is before I give an estimate, and how could these stains be removed? Thanks
