allow about 3 hours for the rapid set to set,some are a lot quicker than others though,you'll know by the feel.

Depends what's more important to you.. Time, or money? If it's your own place, and there's no rush... One coat. If it's a customers place, and it'll cost you more in time leaving over-night... Rapid Set.
