Hi List,

I vacuumed the hoodliner foam from my car because it was disintegrating.

Now I am left with the stickem' that is left over.

Any suggestions on how to get the stickem off..

I tried methanol and it worked marginally well.

Anyone else do this job?

Also anyone ever used the dynamat hoodliner stuff... I see that there are some foil covered foam liners available but was wondering are they made from the dynamat product or some other materal?

Thanks,

Loren Olson

I believe anything you might find that will remove that old adhesive, will also pose a serious health threat. Just take off all the old foam, spray on the 3M adhesive and glue down whatever new hoodliner you decide on.

I just scraped it off with a soft wire brush (carefully)

Loren,
I did this a couple weeks ago. I had most sucess with 3M Release Agent #8971. Even then is was slow going. It would soften the adhesive and I used a plastic putty knife to scrape it into sticky blobs. It took about two hours.
I used a peel & stick foam (1" closed cell black vinyl-nitrile) and I didn't want compatibility problems with any leftover glue.
Worked fine so far.

I do have access to a chemical product we manufacture, that is non-toxic and works very well on duct tape adhesive (that is how all broken things are "restored" down here in Texas) and linoleum floor adhesive. It's just not commercially available. I will try it out and see what it does. The hardest part would be shipping it, but if you are driving through Texas anytime soon......

I think the key is to remove the hood so you can work on it on a horizontal surface, without worrying about things dropping on the engine. GoofOff will do a good job, or did on mine.

I think it's a matter of trial and error to some degree because you don't really know what kind of glue you have on there. Goof Off did nothing for mine. Also, I put a heavy drop cloth over the engine and worked with the hood in place. I didn't want the extra trouble of hood R&R although that would have been the best way to make the hood easy to work on. Somewhere I read that solvents can get on the hood strut rods and ruin the internal seals; you might want to cover the struts too.

Why bother? The new hood liner will hide that mess.

I agree.

Get te grease, oil, mildew and dirt off. If there's residue left; as long as its not to thick or gritty, it'll be OK.
3M # 18 spray works well & seems to adhere to the old OEM adhesive.
I did one last weekend that had residue & the 3M #18 held fast.

Only if the new glue sticks OK over the old glue remnats. Otherwise the hoodliner may fall off and you'll have to start over. It must work out OK most of the time though. I just didn't want to take any chances.

I did mine yesterday. Vacuumed it off just like you. THe glue was a PITA to remove. I covered the engine and the fenders with a plastic sheet to protect the paint and used "lacquer thinner" (sp?) and a spraj bottle to apply. It did a great job removing the glue but it did strip the paint off too. It removed the color layer and fortunately didn't do anything to the factory primer. The new liner covered this all up so at the end it didn't really matter what it looked like under it, as long as the surface is smooth clean and free of any of the old foam. I've cut my liner out of a water heater insulation kit, bought at the local Home Depot for $25cdn (enough left over to do a second liner).

I want to get the old 82 clean so I can repaint inside the hood as well. Otherwise, it probably is not worth the trouble.

Loren,
Orange solvents didn't work for me. I used 1" foam from soundproofing.org. Their PSA worked fine so far. If you have to cut to size make it about 1/2" oversize all around so you can tuck it into the lip on the hood. This will give you some mechanical support in addition to the glue. Dynamat hoodliner sounds OK. I wanted closed cell so as not to absorb liquids, fumes etc.
