First time with Zaino ? Probably you used 'too' much. The magic word is 'very thin coats'. I had the same problem at first.
If it still won't come off, use a damp towel, wipe it off and apply it again very thin coats ( I mean very thin)
Damp the cotton applicators with water or squirt a few drops Z6 and put Z2 or Z5 on it, spread it with your finger, and ready to go.
Humidity is an enemy of Zaino, it takes ages to cure if the weather is humid. If you have the chance to leave the car under the sun, first apply Zaino and leave it under the sun. According to Sal Zaino, it takes about 20-30 minutes to cure under the sun.
BTW, you can use Zaino under the sun.
