Finally gave up on hood pad; anyone want to convince me to replace?
Tired of fussing with my old hood pad on my 91 300D....so I ripped it off. Can anyone give me compelling reasons to replace it? I'll tell you at the outset: I am both glue and detail challenged.

it protects the paint on your hood, and makes the car quieter on the road. it keeps the heat off, and it holds the warmth in the engine bay.

Read my posts on hood liner replacement, reasonable cost and not that bad, used a metal scraper. It's handy to have an extra pair of hands when applying the pad.

Yes, replace for all those reasons
For those of us that are glue challenged, forget trying to clean off all residue and using the "correct" adhesive.
I simply scraped off the big chunks with a plastic scraper and used Liquid Nails construction adhesive. Guaranteed good results but the purists will object. |

Pretty easy job to replace and definitely quieter. Spray adhesive is simple to use.

You'll lose the diesel idle noise-the main reason why I won't run a hood pad

I wouldn't want to bake the paint off... that's why I replaced mine. When I would pull into the driveway after work with no pad the hood would be too hot to touch. With the pad it is cool to the touch

I've not noticed a significant change in noise level but my cats will tell you that the pad definitely reduces engine heat at the hood. When I come home they like to lie on the hood but now they have to find a spot by the vent where there is less insulation. Over the long term, heat can't be good for the paint.

I replaced the pad on 2 W123`s this summer by my self.
Lay a plastic tarp, sheet etc... across the engine. this will keep all the crumbling pad off the engine. pull down big pieces and scrape off what you can with a putty knife. Then I raised the hood straight up, got on the engine and wiped the surface down with a wax and grease remover. a product used when prepping the body for paint. Mark the center of the hood top and bottom with a felt tip marker. do the same with the pad. masked off the windshield and eng bay, then using 3M 8090 spray adhesive sprayed the hood area with 2 coats. then sprayed the pad with 2 coats for good coverage. Let it get tacky. Fold pad in 1/2 (none glued side) and line up the centering marks on pad to the marks on the hood. make sure the top corner is lined up as well as the bottom corner. then smooth it down, then do the other side. Run your hand across the pad with some pressure to make sure the pad is secured to the hood. It did make the 240 a little quieter. Charlie
