urgent quick paint question about spraying

[midcuk]

just adding the final coat of laquer to my front bumper (after wrecking it on a brick wall), sanded down filled primed and coloured ready for the laquer, just tried spraying it on and the bloody stuff is running could kill myself as i was in a hurry) whats the best way to get rid of the run, without sanding the whole lot down again, lacquer is still wet so immediate advice would be appreciated.
