For these strips, as noted previously I suggested L-shaped clear plastic corner reinforcements for drywall, from a home improvement center:

The idea noted above of using a piece of 7mm rope, taped to the fairing, is probably better than mine, perhaps cheaper, too.
Here's a thought, if using L-shaped plastic:
Why not cut it with pinking shears, such that its edge is a zigzag? This might turbulate the cross wind as well or better than a uniform wall height, with less drag.
Thoughts?
Also, in the movie
World's Fastest Indian (now available on Netflix, well worth watching) Burt Munro's motorcycle fairing has a longitudinal ridge similar to what we're discussing here:

I'd assumed it was a simple external joint for the two fairing halves, but now I wonder if (assuming the movie prop is a true replica) Munro had sorted out this crosswind device 50 years ago. Anybody know?
