The wing now has two coats of dark gray primer along the leading edge to seal all the bubbles from the epoxy/microsphere filler. (Applied with a brush, not sprayed.)
Tomorrow I will start sanding it smooth. If there are enough unfilled bubbles, I'll mix another batch and use a Q-tip for spot repairs.
Now it's time for a shower.
