Weatherstrip adhesive

[Mopar_Mudder]

For the rubber molded parts I got from Quirey what do you recomend for adhesive? I am using 3M 8008 and they peal right off, glue not sticking to the rubber at all. I did try cleaning with acetone ahead of time and that made no difference.

Just checked the trunk weather strip I did and same thing, it is falling right off. Glue stuck to the car but not to the weather strip at all.

I applied to both surfaces, let dry to tack and stuck together.

That is exactly what I am using. Same part number as I listed in my post.

Thanks, I misread the part number in OP.
I have also used this with success on door weatherstrip

Yea might go see what else I can find tomarrow, maybe try the yellow version. Have never had this problem before. Maybe a bad tube? Looks fine, sticky and stringy like always.

Here's a thought . . . Ever notice that the factory minimized the use of any adhesive in putting the weatherstrips on at the factory? Meaning they are desired to be installed "dry", unless they might need some additional holding method for a curve or body contour.

Personally, I came to use ONLY high-heat black silicone sealer, if anything at all. NO more "yellow stuff" for me, as it was far too difficult to clean up later!

In the more critical sealing areas, the factory weatherstrip has a lip that matches with a "groove" that it rolls into, holding it in place. Then the white plastic push-in retainers for the less critical places. No adhesive needed.

Myself, as others, usually want to do things "better than factory" when we change things on our cars. Nothing wrong with that! Which is why I like the high-heat (heavier-bodied) sealer for those functions. Eash to apply and easy to remove. ONLY thing is related to its "silicone" component, which can be flaky to get paint to look right if the silicones are used before any new paint is applied. Which can be ONE reason that silicone sealers (many not invented back then) were not used in the assy plants, then or now.

As to the adhesive not sticking to the new rubber items, I would suspect that can be due to a higher silicone content in the rubber composition. Which can make it last longer than OEM.

Enjoy!

This is on a 1962 Imperial. There is not clips, push pins or channel that the weather strip goes in. They were all glued on from the factory, so I have no choice.

You have to apply the adhesive in a thin coat on both surfaces, let it tack up, then apply a small bead to the door frame and immediately put the seal in place.

I found a couple of videos that explains the technique.

That is exactly what I did. You can peal it right off, no glue residue on the weather strip after you peal it off, looks just like new.

That's interesting. I've used that stuff for years for a bunch of different things and never had an issue.

Any chance that's an old tube?

There are different 3M weatherstrip adhesives. There is the Black Weatherstrip Adhesive, the Black Super Weatherstrip Adhesive and the Yellow Super Weatherstrip and Gasket Adhesive. I think it comes in regular Yellow also. It comes in the 5 oz, 2 oz, and 1 oz tubes. I just bought the assorted tubes on Rock Auto. I have some part numbers if anyone needs them.

Yea I have the 8008 which is what all the weatherstrip sellers seem to recommend. They also have an 8011, harder to find though. I found some but a 45 minute drive to get it.
8008 is the Super and 8011 is not, well the 8008 is not being to super to me right now.
8011 says Formulated specifically for use with ethylene propylene diene M-class rubber (EPDM)

I don't think the tube is old. Looks good, just bought it off Amazon.

I'm restoring a 1971 Corvette for a friend. The rear window gasket is glued in and screwed in a few places from the factory. I used Permetex first, it dried Rock F*&%ing solid before I got the the bead all the way around the window frame. I had to use a mixture of gasoline and razor blades along with a wire wheel to remove it. I was highly pissed. I promptly threw it away I ordered 3M and it worked great. I would try a small piece on something else just to see if you have the same issue again before you start with a new product.

Good luck sir

Soni tried the yellow 08001 from 3m and same result, no stick. Couldn't get the 08011 because they closed before I could get there.

 

[volksworld]

you might be fighting whatever mold release agent that was used when they made them ...I would try some different solutions on the rubber, maybe even some water based stuff to find something that will remove it

 

[Mopar_Mudder]

I have some 3M 08011 coming tomarrow to try. But I can try some different cleaners also.

 

[Mopar_Mudder]

Well I think I have success finally. 08011 stuck good on the two test pieces that I did. Ripped the rubber trieing to remove them.
