I found some great reviews on the miata owner forums and thought to give fatmat a try.
Fatmat mega mat review.
Improve audio quality enhance bass combats vibrational distortion.
Megamat stops nasty rattles eliminates vibrations and reduces road noise engine noise and exhaust noise in your ride.
Even more recently fatmat came out with its own butyl based mat the 70 mils thick megamat.
Our new mega mat is thicker and it contains less fillers giving you a true rubberized butyl compound.
Fatmat has finally found a way to offer you a true butyl product and we did this while still making it very cost effective.
Fatmat sound deadener is made to absorb vibrations and noises that travel through it giving you a dramatic reduction in irritating noises.
In addition to the classic 50 mil mat fatmat also makes an 80 mil product the rattletrap.
I ll let you decide if the fact that the new owner s company also sells mfm peel seal has any significance but i have looked very closely at both products and can find no difference at all other than the inked on blue label fatmat added a year or so ago.

Both can cover a truly impressive range of surfaces from 25 to 200 square feet.

Be patient and take your time because this stuff is sticky.
Top up or top down the difference is immense.
Pleased with fatmat definitely worth the money compared to dyno mat.
Somebody in the original fatmat review thread mentioned that fatmat was very similar to peel seal.
