What do you guys find is the best for this. I wanna rip out the carpet in my trunk and line it with it. I know there is two types you can get either spray on or the mat stuff. I don't know about you guys but in my 5G road noise is horrible from the trunk and I want to fix it. I am thinkin of going with the dynamat stuff and stuffing all open spots with like insulation or mono-foam. Any done this yet?

 

its best to dynamat first and then foam over it, but just some dynamat should suffice
