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
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
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 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
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
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.
