Dyna... who?

This stuff works great. Fraction of the cost to Dyna.. and just as good. Very sticky. Used in doors, floors and ceiling. Great product and performs flawlessly. I would highly recommend this.

Awesome, inexpensive alternative to name-brands!
Size: 36 sqft
Awesome. Stuck well with alcohol prep and time to let liquid flash-off. Very consistent, piece to piece. Backing peeled easily when desired. Compared to Amazon Basics, the butyl seemed a little thicker (infinitesimally) and stickier, foil was less thick than Amazon Basics. Very good value. Started with my nice car, but after completing project, sound dampened all cars in the immediate family it made such a noticeable difference in sound level and quality of music from soeakers. Recommended!

Great sound deadening material with easy installation.
Size: 36 sqft, Size: 36 sqft
This sound-deadening mat was easy to install on the roof of my Toyota FJ Cruiser. It significantly stiffened the roof and dramatically reduced the wind noise inside the vehicle caused by my roof rack and lights. I can actually carry on a conversation again without shouting while driving on the freeway.
The 36-square-foot package was enough for my application, with about three sheets left over. The tiles adhered well to the metal without any special surface preparation. I only wish I had done this sooner.
