We just got our BE and I washed, polished, and waxed as soon as we got it. The other day I decided to wash the car. After I finished I had some water spots still on the car. I tried to use quick detailer but that worked a little but I still have some spots. We are on well water and it is very hard. Lots of iron, ect. How is the best way to get these spots off? The paint is still very smooth to touch. Thanks for any advice.
