This took me several days to complete due to lack of time to work on the project. PVC foam sheets were laid on fuselage and trimmed for fit between forward landing gear bulkhead and F-22. Sheets were then glued together with 5 min epoxy. Bottom was the put back on fuselage and weighted down. Lines were drawn inside where all bulkheads met and jig was made to keep shape when transfereed to work bench. The next day I cut and shaped white foam as per the plans and instructions. The following day the foam was glued down with micro and held in place with nails for cure.
