Pretty frustrated. I've tried Revolution Ply, a thin plywood probably 4mm thick and a even thinner particle board MDF type stuff. Nothing wants to make the radius curve from where the ceiling transitions into the walls. I'm not set up to steam anything which is maybe what this job requires? I'm thinking about trying the really thin toungue in groove pine I've seen before figuring that would work since there is some play and the pieces are only 4 inches wide and abot as thick as the Revolution Ply or maybe even thinner BUT I thought I'd ask here first before I waste any more money.
Anyone replaced their ceilings? What did you use?
