Unless you put in on a perfectly flat section of the rear window, the suction cups won't stick even after cleaning and wetting the surface. I could only get it to stick in the center of the rear window which doesn't work for me since I mount my boat toward either the left or right of center. Besides, I have a short roof mounted antenna right in the center which would be in the way even if I tried to make it work in the center.
Part of the problem is that I have a great Yakima bike rack on the back of my car, so I can't use the back window for the Sherpak and loading my kayak. But even when I tried using the side of the car (the Sherpak can be angled in two different ways), the weight of the kayak knocked it off the car windows. And I seriously DID wash the windows first, so that should not have been the problem.
I may try it one more time but, unless I have much better luck, I'll be returning mine.
