Sayed,
Don't worry about it drying. Most of the prep solutions are phosphoric acid based including the one from POR15. They do recommend rinsing theirs. You can also use Naval Jelley. All of them work by eating away the surface layer of rust to get down to bare metal.
POR15 cures by way of moisture. It does not dry like we normally think of paint. So painting over a damp surface only makes it cure faster. The curing by moisture explains why an opened can doesn't last long in storage. Just the humidity in the air is enough to start the chemical reaction in the opened can.
