The best thing to do is wait at least 24 hours before driving or using your car. Before you use any spray adhesive, the surface must be glued needs dust and debris removed from its original location; otherwise, these things will drag around on the new one, which could cause problems in the future like tearing or bubbling. This can easily happen when construction projects are being done, too, so make sure that there isn't anything present during application time; remember this rule: if something was put down for a reason, they don't remove it until after the coating has dried completely because once it does, those issues no longer need to be dealt with either. After all, they've been taken care of already by removing them earlier than necessary.
