Removing superglue whithout ruining the model, the story of my life!
Fortunately for your warboss dried superglue can be removed with an X-acto blade, you just have to cut the biggest part of the glue and sand around the boots and then delicately remove what remains on the boots details and on the cloth using the tip of the blade to pop out superglue flakes (well, I'm not sure if this sentence is right but I don't know how else I could explain it).
