I've had a box of airtabs for quite some time, but I refuse to just stick them on the car and pretend they work.
I've prepared to do a test: attached the airtabs on flexible/removable plastic sheets that I can remove in a jiffy at the road side.
I just need to make another couple of sheets to complete the sides, and double-check with the distributor that the placement is OK.

Above: I increased the spacing between the tabs by 50% to compensate for the 45 degree angle on the rear window.
I may not be able to place an uninterrupted line of them down the side of the car due to contours that they won't stick to. But I'll add a few more at least.
Unfortunately, I've been too busy to actually DO the test yet.
