Deadener is made to stop erroneous noise in the cabin, not magically make wimpy panels stop flexing. It took 3 layers of extreme and dyna-foam to get the sound out of my roof, but now I can punch it and it won't leave a dent. It's all about layers, and using the correct stuff for the application. I won't go into arguing which is better than what, but I used Dynamat (was my only option when I first started) and have been very impressed with it.
