Sound control

Given the wind noise associated with the e9 you might be chasing decimal points of overall improvement but can make some real gains on reflected and direct heat control.

Attached are two paint on compounds that you might be interested in. I've used the Quiet coat and been happy with the results and especially the application procedure. The car came with some areas treated with Dynamat which is probably a very good alternative but much more work to install.

Used Quiet Sound under the rear seat delete.
