Plastic Adhesive for Interior Car Parts

Hello!

A trim piece has come off my 20-year-old Golf 4 due to the recent hot weather.
Specifically, it's located inside the car, above the passenger-side door, and therefore has the same color as the car's headliner.
I'm going to try right now to see if I can upload the image from my phone.

So, the strip is apparently glued to the rubber seal on the door, although I couldn't detect any adhesive residue.
Door seals are typically made of rubber or EPDM.
The strip is on the side that needs to be glued, I think, and it's probably PVC.

I've already tried gluing things together three times.
With the adhesives available.

The first attempt used ordinary office glue, and that just didn't work.
The second attempt was with a type of adhesive similar to contact cement, but I only used a small piece to test it, and it didn't work at all.

Yesterday, I removed the adhesive residue and then glued it back on using spray adhesive, which is actually intended for this type of thing.
Of course, spray it into a small container, apply it with the brush on both sides, and let it dry. Follow the instructions carefully.
It looked good and it also lasted. Then I thought, it's okay.

However, today, in the full sun, the stripe came down again .

Does anyone have any ideas about what kind of adhesive I should use?

Yes, IsoProQ. I used that to glue the headliner in my Audi 80. According to the data sheet, it holds up to 120°C, it's suitable for painting, and – most importantly – it actually held.
Common adhesives hold up to 90°C. Of course, any old residue needs to be removed.

Trim.

Are you sure that's not a profile that's being held in a groove or something similar?

Hello!

Yes, I am. Of course, I've looked at the other side.
The top part is inserted into a slot, and the bottom part, near the dashboard, is inserted into the door seal. There's nothing in between to clip or attach anything to.

I had already glued it on before, and it looked neat then, just like the original.
But unfortunately, it didn't stay up for long... until it came down again.

Yes, I need to see if I can get the adhesive you recommended. Or something similar.

Sure, no problem! Here's the translation:

"Thank you in advance!"

It sticks and holds well, at least with artificial leather; I used it to cover my A-pillar trim.
It's not quite easy to process.

Hello,

There are heat-resistant spray adhesives, but the maximum temperature they can withstand is often only listed on the corresponding data sheet, not on the can itself.

Best regards, Rainer.

Is a suitable adhesive potentially more expensive than a (used) replacement part?

Possibly, this contact adhesive might be helpful: http://www.sabakleber.de/12.html

"For things like that, I use spray adhesive from Tesa. It's important to follow the drying times, and if possible, spray both sides."

Hello!

Thank you in advance for the helpful answers.

Before I double the value of my car by buying a can of glue.
I used some more of what was already available in the household yesterday.

I accidentally found a 20g tube of Pattex Repair-Extreme in my father's desk drawer.
It showed how to glue a detached shoe sole back on.

Apply evenly, press firmly, and leave for 24 hours.
I somehow didn't feel like removing the glue residue from the two previous attempts, which would also be a very tedious process.
Okay, so you put the material on the rubber strip, always 10 cm wide, and secure it with large clothespins.
I ended up using 20 clothespins, and I specifically drove to work today in my T4 van because of the 24-hour waiting time.

This afternoon, I checked it out, removed the clamps, and it looks pretty good. It seems to be holding, and I even gave it a gentle tug.
I thought the same thing last time.
And that's where it failed.

Okay, let's see what happens tomorrow. I'll be taking the Golf to work again, and it will be parked there with its side facing the full sun from noon onwards.
I will let you know if the bar falls down again.
And then, refer back to your valued suggestions.

I can recommend Pattex Repair Extreme. I used it to glue the peeling sole of my sneaker, and it's holding up so far, unlike other products I've tried.

Hi!
So, the bar is still firmly attached.
The adhesive passed the heat test I performed on the parking lot at work.

Looking back, it's funny.
There were no traces of adhesive residue visible when the strip fell off.
It was as if it had simply vanished into thin air...
