It depends how thick of a coat you put on it. If you laid it down pretty thick to get that nice smooth finish, you'll be waiting a WHILE for the inside to dry. The outside will somewhat dry quickly, but then the inside will still be wet. The only way the inside will dry is from the outside, so the outside will be tacky for a while, and there's a good chance the inside hasn't dried much at all.

Either spray it thin, letting each coat dry completely, then wetsand/polish (only after paint has been fully dry for a couple of weeks), or spray it thick and wait about 2 weeks before using it.

If there's one thing I've learned about paint, it's that a good paint job takes time and patience.
