Don't see why not. As I recall it has a skinned finish on the non sticky side. A spray adhesive, like 3M, should stick to it.
But, to be safe, call Dynamat and ask the question to them. After the work to install, would not be good to have it degrade!
We did the full floor and doors of our 07 F150. Really quieted the ride, and the door speaker location supported our Focal's very well with this deadening. Was a bit 'off' sound wise before we added the Dynamat.
Best of luck,
