I had very bad water spots on my dark blue BMW that had set in so deep that home attempts at claying, buffing, compounding, using vinegar did nothing. Brian spent about 2.5 hrs and the spots were gone. I paid a good penny but it was worth it. The paint looks great. The interior job was decent probably because the focus was on getting rid of the water spots. He stayed late to get the job done on the same day that I called. Very satisfied.
