For what it's worth, here's my method.
#1 - Dip the canopy in Future and let cure overnight. (or longer)
#2 - Cut Blue Painters tape into 1/16" strips.
#3 - Mask off the Horizontal frames and burnish.
#4 - Paint the strips with future overlapping the tape.
#5 - First coat is the interior color.
#6 - Second coat is the exterior color.
#7 - Let cure overnight and remove tape.
#8 Repeat with the vertical braces.
I should mention that I do the painting on the canopies with a small brush and acrylic paints. This is all done while working on other parts of the plane.
Hope that this helps.
