I was actually worried about the fumes in my room, so I took my rattle cans to the back alley behind the hotel, and sprayed it on a cold, windy, misty night under the glare of the security lights! The weather did not help my spray job, but I was more worried about the police getting a call about some guy behind the hotel with a spray can- surely a graffiti artist or someone huffing paint- no just a desperate whiffier with a deadline!
