I bought a 1lb. container after a hit an run issue that lead to me chasing them for 40 minutes. They lead me into a neighborhood, stopped, and all 3 got out and came towards me like they had guns (The driver stayed in the car). I was 99.9% sure they didn't or they would have flashed them during the 40 minute chase. I stepped out with a 18" long torque wrench and they all took off running. If I had the spray I would have filled their car up the first light they stopped at but then they probably would have tried to speed off blindly through an intersection and killed someone and it would be my fault...all because they backed into me into a gas station and sped off. The car had a drive out tag.
