SilessBlack 80 mil (2mm) 36 sqft Car Sound Deadening mat - Butyl Automotive Sound Deadener - Noise Insulation and Vibration Dampening Material (36 sqft)

I used this to line the trunk of my miata, it was super easy to work with and seems to have good adhesion (time will tell) so far. I love that it is black so it doesn't appear like you have lined your vehicle in tin foil. Will definitely use again.

This product , to me, is the best application for my needs. Ease of use, quality feel and look.

I was apprehensive going with this product as it wasn’t a brand I’d ever heard of before.I placed it on my doors and trunk and while I didn’t notice a huge difference in road noise from using this product I definitely did hear and improved ent from my sound system once installed.This product does have a somewhat tar like smell when installing but I haven’t noticed it lingering after installation.As far as adhesion I haven’t noticed any shortcomings however I did apply product using a roller.

Good quality got rid of all my vibration noise. Tape sticks very well.

2010 Jeep JK - 4 Door: I did sound proofing on the entire Jeep floor. Easy to install, good quality. Just keep in mind the sheets are folded twice so they are pretty large. I personally like to work with smaller sheets as it requires less cutting. The large sheets would be really good for a large flat surface, but with all the bends and twist, I find working with smaller sheets are easier. I did two other trucks in the past and was less cutting.Just a note to Jeep guys: I bought two cases and it was not enough for the entire Jeep. I was short like 4 sheets, so had to buy another box.Other than that product is great, cuts, sticks and shapes well.
