Will morning dew affect a ceramic coating?
Quick answer: No - once cured, morning dew will not harm a ceramic coating. The only concern is during the first day while it cures, which we handle by keeping the car dry overnight. If dew dries in sun it may leave light water spots - just rinse or wash.
Morning dew will not affect a ceramic coating which has been properly cured. However, if it is allowed to form on a coating which hasn't properly cured, it could affect it.
This is why it is important to have a ceramic coating done by an approved application centre which can keep your car inside, in a controlled environment.
