Also, what if you leave your top down for a few minutes while in the corner store? You may find you no longer own a Windstop. There is no locking device to prevent theft.

My main concern though is the Windstop flying off the SS on the highway. There is an easy fix for this. Lay the Windstop on the floor upside down and move the metal sliders all the way out to the 'latched' position. Drill a small hole in the center of the slider beside the plastic bracket that holds the slider down. Now, take the four screws out of the plastic cap and remove the slider. Using a larger drill than you used to drill the hole, clean up the metal burrs that were left from the initial drilling. Now replace the slider and the plastic cap. Repeat procedure for the other slider. Your local hardware store should sell small locks that will fit the holes that you have just drilled. I got two locks that were sold as a set that are keyed alike.

Now your Windstop will be safe for highway driving and you won't easily loose it to a thief.

The pic is not very good, sorry. It's an econo camera. You'll get the idea though.
