What do you think of that?
I picked fiberglass cloth to match with the silver carbon fiber dash trim kit I might install later, like I had in my black N/A. IMO the 3M adhesive is more user friendly. You can spray 1 or both surfaces for a more secure install. You can bond the media between 30 seconds and 10 minutes. Unlike contact glue, you can lift up the material to reposition and it's simpler to apply. No need to worry about overspray since you are working on a bench.
As far as noise suppression, I can't tell the difference before/after. Don't forget, there is more sound suppressing material on the other side of the headliner, Feels like 2"of foam/cotton combination
