I was redoing my headlights and did it yesterday afternoon as recommended on the bottle and put a coat on one of my headlights. Well when I woke up and checked it this morning I was surprised to see that the whole thing had cracked and was flaking off :x . This is the first time I've actually had this happen and I'm wondering if it was just a bad apply or if it really was dew over night that caused it.

So just how sensitive is veil to water like dew? It didn't rain over night so that's the only thing I can think of that happened was dew set in over night. I know it says not to get in contact with water within 24 hours of applying but short of taking off my headlights that'd be kinda hard
