FWIW, you can get Dynamat Xtreme "bulk packs" with something like 36 sq ft for about $125 shipped, if you hunt around enough. From what I've been told it works very well and the adhesive is excellent - doesn't detach like some other products. I still think a new MB dealer hood pad would be the best bet, maybe with a few sq ft of Dynamat on the underside of the hood before sticking the OE pad on with Liquid Nails (which I prefer over the 3M stuff because it lets you move it around before setting up, and sticks like, well, nails.
)
JMF - 30 seconds? That's one quick 123!
