dynamat, fatmat. same product. what you want to look for is the thickness. There is .5 and .8 mil thickness, obviously the thicker one will do a better job but some people like to do 0.5 to cut down on weight, or two layers of 0.5 for an improved effect. I used 50 square feet of fatmat in my civic trunk and it completely stopped the rattle and increased the sound quality and volume (i also tightened my trunk latch to cut down on shaking). I suggest ordering a roll of fatmat off ebay, it's much much cheaper and I can tell you the quality is great. I will be gutting my cobalt hopefully this summer and installing 100sq feet everywhere in my car to maximize quality and volume. should be sick! any questions feel free to PM me!
