I did a little googling... and didn't find much that I think apply to the type of resin they used. What I really can't figure out is what kind of resin it is. I think it's newer than the coal tar based stuff they used in the 40's, but older than the epoxy based stuff they use now. It's probably closer to the coal tar than the epoxy.
Obviously heat does melt it... and obviously, heat that's not quite hot enough to melt the paint or it would just dribble down, destroy the paint and chip off. I don't think we've seen that.
While I don't know of solvents strong enough to dissolve the resin without dissolving the paint, it might be worth a shot. Break some pieces off and toss them in some alcohol or maybe some naptha and see what happens. Might even just be able to hit it with pressure washer and get a lot off... Gonna have to experiment.
