I picked up my car yesterday after the dealership fixed a couple of rattles. When I went to the car I found that they washed it and of course they did not dry it and found the car covered with water spots. (I forgot to tell the dealership not to wash the car.)I did a search and found that vineger would work and it did except one spot on the spoiler. I tried Finess-it II and that did not work. Is there anything else I could try? Thank you.
