Having messed around helping out friends with racebikes and those patch repairs are pretty straightforward.

I would tape the pieces together as best as possible, sometimes bracing things into the right shape with wooden struts etc. Grind out a strip about 4" wide along the back of the break, thinning it right down near the center where the crack is. Then lay it up with either strips of woven rovings or chop strand mat for more complex shapes. Once it's gone off a quick lick of paint on the inside and then a bit of body filler along the crack on the outside followed up by some touch up paint.

They are race fairings and only need to look good from 10 feet away. We would keep patching them as best we could to keep going untill you had to shell out for a new fairing (Or the bloke stopped falling off).

Cheers
