Hi rifleman, are you talking about the rubber seal that sits next to the glass below the level of the rubber strip which sits above the satin metal finishing strip along the lower edge of the window ? When my window is closed I can see a gap of about 3mm between the outer rubber strip and the glass. ( I can bend it outwards with my finger ) But in that gap sitting below the level of the outer rubber is another seal which in my case is touching the glass. When I fully open the window then lift it a couple of inches and stop it, I can see the lower rubber bending around the glass providing a seal. If I open and close the window when it is misted over or wet, it clears it but not as clear as the windscreen wipers clear the glass. I’m left with streaks like I’ve wiped the glass with a damp sponge. Hope this info helps. Cheers.
