I want to use Dynamat to replace the padding in the rear engine. I think the sound deadening will be better and the reflective backing will be good. Does anyone know what size I have to get it in length and width? I would rip the rotten OEM one out but am out of the local area till a few days. I also feel even if I ripped the rotten one out that is in pieces it would not make a great template. I want to use 3M adhesive to spray it on and hold it down. Has anyone used the Dynamat stuff for this? Thanks all again.
