Its not a matter of not wanting to, I just do not have that data. I will see if I can obtain it. But this is not their first go at sound deadening. We have other products that are manufactured in Germany, they carry the made in Germany price tag though. The products are sold all across the globe. They use GZ sound deadening in places much hotter than most of the US with no problems.
The SA product is not made to be in wet/moist areas like inside of the door cavity. It is made to be on the interior of the car between panels. The ML will be fine in the door cavity.
