Solutions to counter this in the future are;
1) drying with a clean towel as soon as a section is washed and cleaned.
2) spray -on waxes
3) DI water (can get expensive), especially if TDS levels are quite high.
Edit; this can happen regardless of coating.

Agree with all you say. I was curious if spots were under or over the ceramic coating. I have to assume over the coating as I imagine they would have to remove the coating to remove water spots underneath.
