That stuff doesn't work any better than water and time for me with the pepper spray that cops carry so I can't imagine it would would work for the stronger bear spray. The alleged "antidote" they sell for tear gas (CN/CS) doesn't work for me either. The best thing you can do is flush your face with water, blow all the snot out of your nose and stand in the wind. The water won't cool your face long term but it will wash a lot the OC resins away. Also - if you take a blast - when you go to shower, wash your hair bent forward, that stuff will come out of your hair and "head south" to sensitive regions.
