I think you should mention that "hot mud" as you call it does not sand
well like regular mud. It's hard as a rock the stuff I've seen anyway.

"Quick set (Hot Mud): This comes in bags. It's powder that you mix
with water. Ranges in drying time from 5 minutes to 210 minutes. Be
careful, once it starts setting up, there's no stopping it, and it is
very hard to sand."
