The exterior moulding seems to be coming detached around the backseat passenger window, like a glue or sealant strip that's coming unmoored. Is there a recommendation for reattaching this, like a particular sealant I could use without having to go to a repair shop?

I have a 2013 r55 Clubman. The windows don't seal as tight as they should at top and sides. I've seen on some models when you remove the door panels there are 2 screws that will adjust the Rake and will put more pressure on the top seal. I don't see those on mine. Are they located somewhere else...
