I installed this Metro roof/door seal back in August. Doors were extremely tight and difficult to close...but I got them closed and they've been closed since Aug 31st. A couple of weekends ago, the painter goes over to do the final adjustment on the door glass, door striker, etc. This end portion of the roof seal is extremely thick and it is what is giving the most resistance of allowing the doors to shut. The glass is adjusted as far back as they can safety be without hitting the trim at the rear of the door jam.
