I once used it (gaps & cracks, type) to glue down part of a dash board cover in a car in Az. during the summer. NO WATER vapor in the car! Very dry area. It sealed it down and I left it weighted over night. It's on like steel!

Another note, I once tried to use 5200 to glue on a rear view mirror to my windshield (in the San Francisco Bay area). Left it for over 3 days and it NEVER stuck. 5200 needs moisture to cure.
