I would not use a commercial grade 2 part foam.They make one for models.Its a low E ok.The stuff you use for a real boat or home.Will expand way to much per volume an will blow that frame apart.What most do an I would do on that balsa frame.Is use a closed cell Ridgid foam board. An cut an shape It. To fit between the bulkheads.Make sure It Is a closed cell foam!!!If not the open cell absorbes water an that's not good...

Hey also looking good...See you put In some cross members to stiffen It up.
