Gorilla Glue is polyurethane I think. I mean the thick viscosity type of 
cyanoacrylate glue you can buy for instance in hobby shops, like this 
stuff: 
http://www.hobbyking.com/hobbyking/store/__7174__HobbyKing_Super_Glue_CA_50g_1_7oz_Thick.html

It doesn't really matter which brand, what you want is cyanoacrylate and 
not the runny kind. Any decent shop selling models should have it, or a 
Games Workshop store (I think it is the preferred glue for building 
Warhammer figures).
