Hi Just brought a 1998 Z3 1.9 wondered if you can help? The roof seal (the rubber seal that runs up the A pillars and across the top of the windscreen has perished. I have managed to locate one from a scrap dealer - this one has some sort of adhesive on it on the underside. Can anyone advise if it need to apply some sort of adhesive/gunk to the seal before I fit it and if so what? I presume it shouldn't be something too strong as I wouldn't be able to remove the seal in the future! Any help appreciated!
