My local "expert" recommend DAP contact cement... This is the kind of stuff you put two layers of on. One layer on the pad and one on the hood.
Then when they have both set up a bit, you press the two together and use a roller to get all of the glued area.
I will be trying this myself next week.

Factory uses 3M or Permatex weatherstrip adhesive... yellow... (at least with yellow, if you messed up a bit... won't look bad... black is other choice)
You will need a big tube to glue it.. glue on hood and glue on pad... let dry a bit... then stick em together...
Problem with all other adhesive is that the heat from engine and sun will weaken it..

I ordered mine from Randy at EPS (www.epsparts.com) in CA. You can also find some on eBay depending upon your model.

3M makes a Heavy Duty Trim Adhesive, which is stronger than their regular Trim Adhesive, in a spray can. This is a great adhesive to use, provided that the underside of the hood is prepared properly. Most replacement pads fall off due to inadequate cleaning of the underside, mostly not removing all of the old pad and not using enough adhesive which will cause sags. Don't skimp on the adhesive and use a burnishing tool, like a roller (a paint roller works well) to get good contact with the hood.

I used the 3M spray adhesive to put a new pad on 300SD, worked great!

I used 3M Super Weatherstrip Adhesive in a spray can. It is the same yellow "gorilla snot" that comes in a tube, but sprays on. It is rather expensive at over $10 at the auto parts stores.
I taped newspaper around he hood edge and over the engine and windshield, but the can has a very well controlled spray pattern, so it was not really necessary.
I paid $86.10 at the dealer for a new hood pad for my 1987 300E. Mail order is much cheaper.
Unsnap the hood latches so the hood is perched straight upright. Before spraying adhesive, test fit the pad and mark the enter of the hood and the center of the pad. Spray the adhesive on the underside of the hood after scraping away the old material and cleaning with some cleaning solvent/paint thinner.
Lay the hood pad over the top of the engine after spraying adhesive on the underside. Wait the recommended 10 minutes or so on the adhesive instructions. This waiting period is very important with contact cement.
Lift the hood pad up and start attaching it at the top center (under the grill at the front) making sure it is straight and work it down and out to the edges. I found that a paint roller was a great tool for making certain the adhesive on he bottom of the cushion like material bonded with the adhesive on the bottom of the metal hood.
I put my new hood pad on in about 30 minutes and it has stayed attached for almost a year including our present 100+ degree summer.
