I installed the dynamat in my 1996 camry. I did the front doors, most of the roof and half of the trunk. I didn't realize how quickly I would run through the product. I don't have a stereo installed yet, I decided to do this first, also just to try and make my daily drive that much quieter. It is a little quieter but it didn't make as much of a difference as I thought it would. But to be fair, I still have the floor to do, which is definitely where most of the noise is coming from.I didn't buy/use the wooden roller thing that is recommended. And I don't think it's needed, but might make it a little easier when doing large open areas like the roof, floor, and trunk but would be useless in cramped spots like inside the door panel. I warmed it up with a blow dryer, and my hands and did ok.
