Critical to Replace any Deteriorated Tacky Adhesive

I am going to replace my 2000 Saab 9-5 window regulator rollers as soon as I have a plan to handle the adhesive inside the door(s).

There is a sturdy membrane fastened inside the door that is removable. The adhesive performance is critical to assure that the side airbags will activate. Air pressure triggers this. Saab is out of business and expertise is difficult to find.

I can certainly peel back the lower half and replace the rollers. Every video I have seen shows the adhesive randomly releasing both from the film and from the door, so the "bead" is interrupted. They say it can be reused in the narrative but I am astonished at their lack of caution. Plus, there are never close-ups of how to mend any tear in the adhesive bead.

I need to characterise this adhesive. My initial guess is that it acts like a librarian putty and/or toilet wax seal, perhaps plumbers putty. I want to know the right words for it - what is it called?

When I do the repair, I may find the the film is already loose and the adhesive is contaminated. So I want to understand how to clean, maintain, repair, or replace this.

I know the membrane can be mended with the right kind of tape (but certainly Not packing tape).

Since this is a GM version of a Saab, I may be able to purchase some squeeze tube product, but I don't see the bead on a door parts diagram.

Any insights would be appreciated.
