Advice please - Doors

[Alan Surrey]

Please could you guys with first hand experience kindly advise me?
I have stripped the front passenger door of my 2008 QP to access, remove and repair the window regulator assembly and, all being well, will begin reassembly in the next couple off days.
The advice I need is about gluing the membranes back into place. How do I do it? I think I need to make a continuous waterproof seal.
The biggest of the membranes looks like the photo. All are glued to the metal carcass of the door with a long, continuous bead of something like putty but adhesive and elastic. The bead is about 5mm thick and, being continuous, affords a watertight seal, protecting everything inboard of the membrane from any rain ingress (via the window glass and rubbers.) To detach the membranes from the door, I had to cut through the putty with a scalpel, cutting parallel to the surface of the door, so that some putty remained on the door and some on the membrane. The second photo gives some idea.
I can't see how to glue the two back together: my cutting was somewhat irregular, and in any case, what adhesive can safely be used on these materials?

All advice gratefully received.

I’m not sure if this helps, but on my E39 BMW using a heat gun on the membrane adhesive softens it to the point where you’re able to reuse it again and reestablish a continuous seal. Note this was advice I found on the owners forum, I think I ended up using Tiger Seal or something.

this is what you need, you can buy it from bodyshop/paint suppliers

Many thanks guys.
I now feel much more confident about the next stage of the repair process.

I had to redo membrane seals on my daily shed Jazz - rear footwell puddles!
Any acrylic gun-applied sealant will do. There's automotive types but for the Jazz I used Unibond Weatherguard window frame sealant.

The materials suggested above might be more "proper" though

^^^ what he said. Any old tube of sealant.

show us some pictures once you have done, will your knuckles look like fight club?

Terrific knuckles. Real Maserati ownership ones.
Photos ( of the work being done) to follow, so the next one to repair his window regulator can avoid some of the pitfalls that I did not....
