Sound proofing is not in the manual. It adds time and money to the build. It can be difficult getting into some of the nooks and crannies of the car. This is an optional task.

This is the 50 foot roll. It is easily cut with an utility knife. The white backing is a wax paper for the adhesive.

For cockpit sound proofing, I decided to go with B-Quiet Ultimate. Dynamat is the industry standard. For sound proofing, the Dynamat product is Dynamat Extreme. B-Quiet Ultimate basically has the same sound dampening properties. It is lighter weight than Dynamat Extreme, and it costs half as much as Dynamat Extreme. With everything else about equal, cost was the deciding factor.

I use a ruler, T-Square and utility knife to cut the pieces.

I purchased a 50 ft roll. The website provides the following description:

B-Quiet Ultimate is a viscoelastic deadener with a supercharged butyl based adhesive. With an aluminum constraining layer and an unique composition with suspended mineral particles it has been proven to be extremely efficient at the conversion of vibration to thermal energy. B-Quiet Ultimate is extremely flexible which is very important as it allows it to properly adhere to a contoured panel.

There are many funny shapes and weird contours inside the GTM cockpit. I find B-Quiet Ultimate easy to cut and mold as necessary. I am working on the front and rear floor panels that are part of the chassis. I need to read more about the middle sheet metal panels before I sound proof this area. I also need to rebuild the passenger footwell post AC Evaporator install.

This is the rear floor on the driver's side. There is a slight over lap between the pieces to handle seams.

Consideration: I am adding this note in a number of places on this nlog. If you purchased AC, then install it first!
