You might want to check to see if it's legal to spray someone with Bear Spray in your area. No use getting in trouble yourself.
I have a Sheriff friend who was just issued "TOP COP".
I think it is 5000 scoval units, but can't remember for sure.
I asked him to spray me as he said it had one of the worst burns that he had ever got from OC.
I can tell you it was the worst I have ever been hit with, and I've been sprayed more times than I care to remember (Retired LEO of 15 years, 3 yrs in a prison). It gave me one heck of a headache also.
Give the Top Cop a try. It's pretty nasty stuff.
I'm not sure if it's available in different strengths or not.
Be aware that some people are not affected much by OC, especially people who have done hard time. If you can find it, an OC-CS mix might be a good choice also.
Be aware that oil based sprays can light a person on fire if sparks or open flame come in contact with them right after being sprayed.
It happened a couple of times where someone was sprayed with an oil based OC then taised. They actually caught on fire. Sounds like it could be fun to watch if the guy really deserved it, but sure could get you into court
