Trimmed previously selected 4 x blue foam bits for nose top.
Made 1.5" square foam fillets for inside corners hinted at in plans.
Assembled all with water-based expanding can foam, if it works is much easier to clean the residues with water instead of acetone. If it doesn't do the job will disassemble before glassing and refit with micro, but think this will be easier to shape. Made a test piece.
