So this absolutely works! I just drove after the car was sitting in the sun (when all of the problems happen), and I had no creaks whatsoever. Not a sound from the shelf or C pillars or anything, even through dips and around fast corners. I replaced the clips in the C pillars and felted every exposed surface. So glad it was worth the time!
