Using 60 grit sandpaper, sanded canopy fairing to general shape. Used a flat sanding block for sides and a small propane tank cylinder for the center radius. Ironically, the cylinder had exactly a 2" radius so worked out fine. Using exopy and microballoon filler, filled low spots and let dry overnight. Sanded further and applied additional filler. (page 34-15, partial step 5).
