   -------------------------------   
   What urethane molding compounds do you suggest?   
      
   In the mid 60's I was a lab tech testing Adiprene molding, but I haven't   
   kept up since.   
      
   One part of the testing was dissolving it in toluene, in large open vats   
   that spools of nylon webbing were dipped in to make a leather alternative   
   for industry. I discovered that I don't get high on glue solvent and don't   
   want to breathe much of it ever again.
