yes pepper spray does make you stop and thing... F*&K that stings..
What about a can of bug spray?
Down here you can buy PS, I think you still can but it has always been illegal to carry it. Like a few things down here. Can buy them but not allowed to posses them. Can't say I've seen any for a while but I'm sure you can still get it. Maybe only from bong shops or other places you can buy stuff your not allowed to posses.
