Second Skin Damplifier Premium Car Sound Deadening Material (1mm) – Butyl Rubber Auto Sound Deadener Mat (10 Sq Ft, 5 Sheets) – Made in The USA

Made a big difference and I plan to buy more! Made in USA is a must!

Very easy to use

I installed this mat in my wives Mustang. It is easy to work with, cuts easily with scissors, and works well. Using a roller is an absolute must. It made the new speakers I installed sound great.

Nice product to work with helped tremendously in my truck and my daughters car trunk

I wanted a sound deadener for underside of riding mower hood, I choose this because it was recommended for under hood higher temps and I wanted something with a black color which I thought would be better than a reflective color as I didnt want to reflect heat back onto the engine. I used denatured alcohol to wipe the areas clean as possible first then used some 12 aluminum foil to make a template, marked the sheets and cut them for some curved edged sections. I slit the backing at the center and peeled and folded back the middle and lined it up with center alignment marks then a small wood roller to press it down and adhere it, peeling more area of the backing in small steps and got it down well that way. Two diagonal cuts in 2 sheets made up better irregular coverage (4) pieces for the sides of the hood. I actually used the 2mm, 4 sheet kit, I bought directly from their site.

very non dirty, if you know then you know, clean
