amazing product
Model: 36 Sqft
actually surprised how great the product is and way better priced then other companies. its sticky and also has thickness enough to cover metal parts on cars. i would recommend 100% just ordered another 18ft for the rear deck and to have some extra! does not smell. easy to install and helps stop vibration.
