A worthwhile addition to just butyl itself.
Model: 197mil 31 sqft Car Sound Deadening Mat
I used this as a topper to butyl sound deadening material on the floor and side panels and am very pleased. It was generally easy to use. It is very sticky and cannot be easily repositioned as the foam will separate from the sticky side if you try, but its not a big deal. I have yet to run the car but the panels are much quieter when tapped on vs just the butyl alone, and this stuff weighs almost nothing.

Easy to install and great value.
Model: 197mil 31 sqft Car Sound Deadening Mat
Very easy to cut and install with the rollers I bought separately. It adheres well even though I was installing it when the weather was closer to 40-50 degrees. Definitely helps to deaden the sound from the bare sheet metal.

Garbage
Model: 197mil 31 sqft Car Sound Deadening Mat
Straight garbage, I tried to cut corners on cost of building an spl car and should have stuck with dynamat or something like that. This is NOT for sound deadening…… Garbage product!!!
