MY chosen form of adhesive for such an application would always be 'Evostik' and I dont think it would suffer in the way you describe, Denis?

Some water used to find its way in this way (often dripping down the neck of driver and passenger), but not since I removed the rubber strip that was fastened to the back of the sunroof (probably not original/possibly a poor copy). This appeared to be helping the water to find a way in.
The metal strip that used to trap the rubber strip in place is still there, but hidden by the overhang of the roof panel - and it must be the combination of the 'step' provided by the frame sealed and screwed onto the roof plus the overhang of the sunroof panel that keeps the rain out.
Colin, I too am not sure how they differ. I know they are different, though that may be by dimensions only and the broad prinicple remains the same. On my car I have set the rail assembly (including the transverse rail to the rear of the opening) on a thin bed of mastic, so that should be sealed against water ingress. Similarly, on the rails themselves, just to the rear of the transverse portion, there should be drain holes that let any water that gets that far run away. I cant imagine a situation where the addition of the rubber trip would actually make things worse? Unless there was some 'capillary action' that caused the water to travel up the underside of the rubber and then drip off?
Maybe?
At the moment I am summoning up the courage to add the vinyl to the panel having put the hessian and thin layer of wadding in place. It is the cutting of the corners that frightens me...
