Probably annoying as shit to get to stay in place. But hey, it cheap. Buy it and try it out.

 

What I did on my old truck (94 Mitsubishi Might Max with a Lifetime Super Sport aluminum shell) was to get some foam garage door weatherstrip from Home Depot and glue a single, continuous piece from about three inches below one side, up around the top, and back down the other side, leaving about three inches below the bottom edge of the window. I glued it onto the truck's window frame, but it could have just as easily and effectively been done on the shell's frame, as well. I could have glued it all the way around the bottom, too, but I wanted fresh air.
It worked perfectly. I was able to have all the advantages of a boot and a sliding window, for about $10 worth of weatherstrip and $5 worth of 3M weatherstrip adhesive. I stopped all the debris from collecting between the windows, kept the weather out, and yet still had fresh air from where it was not sealed up along the bottom.
I just got a shell (fiberglass Snugtop) on my new Taco, and am likely going to do the same with it.
