Thanks for all who have looked. Per the request I've uploaded a picture. You'll see that the photo is actually the back window, but it's easiest to see on the glass - even though the spots are all over the car. You can just barely feel the spots, they seem to be on the surface. Hold on to...
We recently purchased a beautiful dark blue 330ci (with the navy top) but soon discovered that the previous owners did something that left the entire car (paint, glass, mirrors...) with small spots. They aren't white like hard water, but clear. We've tried washing, gently rubbing with no luck...
