I’m also planing my headliner for the 37. Nothing available pre made. The closed cell spray foams wouldn’t be to expensive. You would need to do it in multiple stages. With a form backed with Mylar so sticking won’t be a problem. Maybe in 6” sections between roof braces.I’d use a low expanding foam. But be careful it expands with a lot of pressure. One end of form needs to be open. The commercial spray cans are a lot cheaper but you need to buy a spray nozzle to snap on the can.
I’m leaning more toward a ridged headliner like a foam board like Sintra or maby ABS covered in cloth. I m not sure it will follow the full curve of the curve of the roof. I don’t think Luian plywood will make the bends without breaking?
