Yello, I like exactly what he did. Just enough CF to show. I also like the ‘insert’ look, showing the support structure-has me cooking up some ideas that require wires....
C54ME, I saw someplace that did the embroidered logo. Need to find that again.

Ok, is there anyone who has done their own painting/decorating? I don’t have the skill with airbrushing to attempt that but I’m well versed in stencils, mats and taping. Trouble is won’t any or all of these methods that use adhesive pull the fuzzies out on a new hood liner?
Chas...I think you may have me confused with someone else? I do not have a hood liner...I have the MCM hood 3 posts up and I gave you a pic of the carbon fiber underneath the hood...MCM hoods do not have a liner...

First, the underside of the hood has to be clean. I use 3M 08984 Adhesive Cleaner. That will remove most types of "sticky stuff" from previous failed attempts to get a hood liner stuck to the hood. It won't totally remove certain hard adhesives. For some reason, amateur Mercedes mechanics/body guys like to use "Liquid Nails" brand adhesive and it dries to rock hard yellow chunks. For those, I sand them down and take any weird points and peaks off the stuff, but if it's not cracking or coming apart, I just leave a smoothed over lump of it. The foam hood liners will conform to it and I don't like having to damage the paint and do paint repair to prevent corrosion behind the hood liner. I just clean the remaining smooth lumps with the 3M cleaner.
Once the hood is clean (and the liner must be cleaned as well, using the same cleaner, unless you're installing a new liner), I use the 3M 08090 Super Trim Adhesive. If you follow the instructions, the stuff is great and I've never had a liner come off (until the foam is literally disintegrating). But the instructions aren't always obvious, and many people are lazy and don't follow the recommended procedure. You have to apply 3 light coats of the stuff to each surface (both the hood and the liner). Allow each coat to dry about 15 minutes (the official recommendation is 5 minutes to 60 minutes). I just alternate between the hood and the liner, coat one, then coat the other, repeat two additional times. I also spray up and down on the first and last coats, and side to side on the second coat, to get better, more even coverage. Allow the final coat about 15 minutes to dry before putting the things together.
Use a roller to press the pieces together. If you have the hard roller that fiberglass guys use to press cloth down in multi-layer fiberglass layups, that's the best kind of roller to use. In a pinch, a narrow "trim" type paint roller will work, but it's hard to get enough pressure with one of those.
The 3M 8090 Super Trim Adhesive is quite heat resistant and is pretty much designed specifically for hood liners. It can also be used for vinyl tops, interior carpeting, heavier roof liners and any heavy trim pieces that might be exposed to heat and/or sunlight.

Some of you have removed the hood liner, and went with paint, so the obvious question would be,what is the purpose of the hood liner?
Obviously GM must have felt it was necessary, or would not have installed it on the car.
One more thing, is it used for sound deadening?
When I am standing next to my car, with engine running, I can't even hear the engine running.
I would assume the hood liner is creating a noise barrier.
Those of you who have removed the liner, do you notice the engine noise, especially while inside the car?

From a close friend: Here’s what I got back from Roc. I’m thinking maybe he’s right.
I would not, personally speaking now, put some kind of fill in material on the underside of the hood. My concerns would be long term viability (would it eventually dry out and start falling into the engine bay for example), does it add significant extra weight (struts do wear out and not support hood but extra weight hastens that) and lastly what if you want to change the liner and/or the hood?
My attitude with hood liners is that they reduce noise, absorb fluids that may spray out and protect the underside from cosmetic and minor physical damage. I would not run without it and if you are looking to making it look nice why don’t see if you can find someone who is at talented artist, maybe not professional but a good amateur and see if they would paint one for you and start with a brand new one. Other than knowing that it’s useful and I believe necessary detail, I’m not an expert at decoration there. My Z06 has the Genuine Corvette Accessories one that GM sells as aftermarket, only because GCA one gussied up my car for a display when they couldn’t get a company car to an event. They sent various parts to me, I installed them, and then let them up the car on display and do a walk around. My Z is more of a mule than just a retail car since they tried out so many different things on it.

From personal experience and observations on many cars, I can also add that a hood liner/under hood insulation does seem to preserve the paint on top of the hood. I see more clear coat pealing issues and more paint issues on the hoods on older cars that are missing the hood liner than I see on cars that have maintained the hood liner (and replaced with a new stock item when it got fluid soaked or just started flaking apart). Unless it's an all out, built for max speed race car, I try to keep a hood liner in place. It keeps the noise down, and the engineers at the manufacturer put it there for some reason(s).
