I bought this for my Cousin to put into his muscle car. Personally, I think it was a waste of money, but he wouldn't listen. He likes it, but most likely a placibo effect.

Used this on my honda fit and Dynamated the spare tire wheel well. removed the tire well covers and sheeted the tire well. A dramatic improvement in road noise. Estimate a 3dB redcution at 30 mph. I Plan on putting some more Dynamat on the spare tire well cover in the front wheels. That should yeild a more few db loss of road noise. Now long road trips will be far more pleasant.

My 2004 Honda Civic had some rattles, but mainly suffered due to the thin metals in the trunk and door areas. Despite installing new speakers and a powered sub (an Infinity Basslink), my music really sounded muffled, with a metallic tinge and a lack of mids (especially in songs with vocals). Driving on the freeway always meant turning the volume up, which made the music louder but didn't help in terms of quality. I tried stuffing the area behind the rear wheel wells (on the sides of the trunk) with foam, but that didn't help much.
I bought two of these bulk packs back in January but didn't have the time to put them in until late July. I didn't use a heat gun, but did set the sheets outside in the sun for a bit before using them (which did help make the adhesive stickier). I used some odd things (scissors, a chisel to push down on hard to reach areas, the rounded handle of a screwdriver) as well as an old wooden roller, which is basically a necessity if you want the Dynamat to go on evenly and look smooth.
I planned to Dynamat the trunk, rear deck, all four doors and under the rear seat area. Taking out all of the lining, popping out the door panels, etc. took a while, but as I had done it before it wasn't difficult. I eventually also Dynamatted parts of the center console and even under the steering column and glove box. It's recommended to use denatured alcohol to wipe down the metals beforehand, but I just used rubbing alcohol and a microfiber cloth. ... Read More

Where I went wrong was not buying the bulk to save money, be sure to have a wooden roller and a heat gun. I did my application on a really warm day and the mat was flexible and sticky but still need to be rolled into contour areas. I bought the bulk package to line the 4 doors of my 2001 Chevy Blazer since i was in the mood to fix it up. The product works as stated, easy to apply and reduced the door vibration as well. Road noise was reduced as well, I will be installing some under the floor mats to quiet down more road noise.
