Completed a trial tuft test yesterday in some high wind on a 2010 Honda Civic. I was astonished by the difference the crosswind makes on the vehicle. I wouldn't have thought the shear on the passenger windows would be as much as it was.

I plan on completing the "initial look" 2012 Prius tuft test this afternoon. Any recommendations from some experience before I start?

I have a GoPro cam to record from a secondary vehicle.
The yarn is bright red and nicely visible and is held by some tacky masking tape (so I don't damage the paint).

I'll make sure to post results and discussion after reviewing the video.

So... Suggestions? and anything you want to see in particular?
