I live in very dry northern Montana and I use ATG, Scor-tape, and Scotch Quick Dry Adhesive (liquid glue). I've never had any issues with stuff staying together (of course, we don't get near as hot as Arizona in the summer but it gets to 55 below wind chill factor here in the winter!).
When the temp edges upward, I have noticed that I have to "burnish" or rub the Scor-tape in place on both surfaces. It's just a habit now to do it with both Scor-tape and ATG.
