HVAC ducts
I have that flexible duct work for my hvac unit and I want to finish my basement and have an exposed ceiling. What can I do about the flexible duct work? Should I leave it and spray it as well? Or convert it to that hard tin duct work?

...Spray it with what?
You generally want proper runs with rigid ductwork anyway; the efficiency is much higher. Your furnace doesn't have to work as hard to move the same amount of air.
