This is one of those situations where I give advice on a strategy and you make it work for your classification. In other words, if I tell an actor or a costume designer to do a set visit, because that's where they do their work (on set), then you would ask yourself...
"where do I do my work?"
And when a little voice inside your head pops up and says, "at post houses like Todd-AO or Warner Brothers," then instead of a set visit, you would visit the post houses. You use the same techniques to get post house visits that you would use to get a set visit. You also use the same etiquette.
