After letting the fiberglass cure over night, I popped it off the mold. Trimmed the edges close with hand shears then took it to the belt/disc sander. Then I covered it with filler and let that cure for several hours. Then the fun began, first I did a rough clean up with a cheese grater and moved on to the 80 grit sanding block and progressively through 120, 220, finishing with 1000 grit paper. The final pic is the part covered in primer ready for paint. Before painting, I'll need to fit it to the servo drilling mounting holes and maybe some sort of weather stripping.
