But he had one useful point though, is it definitely the oil of  
wintergreen doing the work?
I mean if it is only present in small concentrations in those substances  
used chances are it may not be the active agent, do we have any assurance  
it is?
I was told a long time ago glycerin can make rubber soft again. I dunno if  
it is  true, and for which kinds of rubber, but i couldn't see any change  
when i soaked something for weeks.
