Whats the best way to stick the rubber windscreen seal back on?

As above really, mines come lose and curled, I've tried using seam sealer and really strong tape to hold it in place but its not strong enough and it still curls!!!

Any ideas?

The Disco 1 windscreen has four mouldings which are slotted onto the glass edge before the glass is fitted to the car. The two uprights (A-pillar) have a double sided taped backing to help keep it in place.

Despite the rubber appearance, the mouldings are actually metal trims, coated with a PUR compound. If you have one curling in the wrong direction, you'll have a bit of a job trying to curl it back without kinking the metal, and do it all successfully with the screen in situ.

Its just the top rubber strip, the screen was leaking slightly and I had to pull it back to repair the leak, since then it doesn't want to sit right

Its doing my head in.
