## Description

AggSound Car Sound Insulation Mat 275mil 6sqft

Review: bought this product to use as sound insulation for an inexpensive dishwasher- easy install and really reduced the sound.
Review: Very delicate, tears and deforms easily. Strong glue but very messy. Cannot be lifted and reapplied, so get a right the first time
