It looks like it just takes longer to dry. Most contianers of wax have a guide on when to put something on. It has been my experience to stay away from freezing wheather.
Boy the directions for Zaino looks to be a pain to follow. I just use Turtle wax for $2.98 and throw that stuff on without all the fuss.
