No, not when applying a small puddle in a depression and rubbing it  
around. No softening, no stickyness, nothing, with my (european) denatured  
alcohol. Vacuum formed polystyrene cups (white, solid no foam, for dairy  
products) also show no reaction either. I believe they are also plain  
polystyrene.

Seems a bit silly to me to denature it with something that dramatically  
reduces it's applications. May be why IPA is used in the US instead.
