After 5 minutes of sanding with a 3M foam sanding block.
After 30 more minutes of sanding and shaping it is just about what I want. Thought I would see how it looked on the plane.
And to finish the night off I brushed on my first coats of water based polycrylic by MINWAX.
From here I will sand and then apply more polycrylic. I will do this a few times before I prime and paint the canopy. My reason for doing this is two fold. First, I will achieve a nice finish. And second, it will protect the foam from melting when I apply the spray based paint. More photos once I have it primed and painted!
